68Ga-PSMA Uptake in Angiolipoma.

Ga-PSMA PET/CT is an imaging technique used in staging and detection of prostate cancer. However, enhanced uptake on Ga-PSMA PET/CT scan has also been ascribed to other malignant and benign lesions. We report on a case of a 56-year-old man with treated prostate carcinoma who had a Ga-PSMA PET/CT scan for restaging. Ga-PSMA uptakes in the prostatic bed and in multiple subcutaneous lesions were seen. Histopathology of a subcutaneous lesion revealed angiolipoma. It is important to be aware of the existence of ...

What is the best timing of repeated CT scan in mild head trauma with an initial positive CT scan?

Mild traumatic brain injury (MTBI) is among the most common causes of A&E admission. Current Guidelines have clearly evidenced risk factors and neurological signs that should suggest a head CT scan at admission and indications to the first repeated scan. However, the role and frequency of further repeated CT scans after an initial positive scan is still unclear.

Incidental Detection of Meningioma by 18F-FMAU PET/CT in a Patient With Suspected Prostate Cancer.

We report on an incidental detection of a meningioma on [F]-2'-fluoro-5-methyl-1-beta-D-arabinofuranosyluracil (F-FMAU) PET/CT scan that was performed during a prospective investigation of F-FMAU PET/CT for targeted biopsy of potential sites of tumor in men with suspected prostate cancer based on elevated prostate-specific antigen level. Neither prostate multiparamteric MRI nor F-FMAU PET/CT localized small volume Gleason 3 + 3 tumor deposits. However, an incidental focal high accumulation of F-FMAU was obs...

Subtle excess in lifetime cancer risk related to CT scanning in Spanish young people.

CT scan is a life-saving medical diagnostic tool, entailing higher levels of ionising radiation exposure than conventional radiography, which may result in an increase in cancer risk, particularly in children. Information about the use and potential health effects of CT scan imaging among young people in Spain is scarce.

Is endoscopic surveillance necessary for patients who undergo total gastrectomy for gastric cancer?

There have been only a few reports investigating the clinical efficacy of follow-up endoscopy for detection of recurrent gastric cancer after total gastrectomy (TG). We reviewed the records of 747 patients undergoing TG from 2003 to 2012 and enrolled 267 patients (70 with early gastric cancer (EGC) and 197 with advanced gastric cancer (AGC)), who received one or more follow-up endoscopy and contrast abdominal computed tomography (CT) scan. We found no tumor recurrence in the 70 EGC patients during the mean ...

18F-DCFPyL PET/CT in Oncocytoma.

A 76-year-old man with biochemical failure after primary radiotherapy for prostate cancer had no malignant disease detected on Tc-MDP bone scan and diagnostic CT. Prostate-specific membrane antigen (PSMA), a type II transmembrane glycoprotein, is overexpressed in prostate cancer cells. The PSMA-targeted F-DCFPyL PET/CT demonstrated lymph node disease and photopenic defects in the left kidney associated with a cyst and biopsy-proven oncocytoma. Prostate-specific membrane antigen is expressed in the neovascul...

Addressing Survivorship in Cancer Care.

As a disease, cancer can affect an individual's well-being, from physical to psychological, social, and even spiritual wellness. The cancer survivor population must navigate a complex, constantly evolving field, with the assistance of their care team, to conquer the disease. To address the unmet needs of the cancer survivorship community, NCCN conducted an environmental scan of existing and emerging aspects of survivorship cancer care through stakeholder meetings with survivors and patient advocacy groups t...

Whole body bone SPET/CT can successfully replace the conventional bone scan in breast cancer patients. A prospective study of 257 patients.

Single photon emission tomography/computed tomography (SPET/CT) is usually recommended after ambiguous whole body bone scan (WBS) findings. We investigated the value of routine 2-field ("near" whole-body) SPET/CT application in breast cancer (BC) patients.

68Ga-Prostate-Specific Membrane Antigen PET/CT in Triple-Negative Breast Cancer.

The prostate-specific membrane antigen (PSMA) is a transmembrane protein with elevated expression in prostate cancer cells. Breast cancer also shows PSMA expression. We present the case of a 30-year-old woman with triple-negative bilateral breast carcinoma who underwent bilateral mastectomy, chemotherapy, and radiotherapy. She developed a left chest wall and liver recurrence after primary therapy. Her recurrent disease was also triple-negative. In view of the known poor prognosis and very limited therapeuti...

Benign Esophageal Findings on 68Ga-Prostate-Specific Membrane Antigen PET/CT Scan.

In 2 high-risk prostate cancer patients, PET scans revealed focally increased Ga-prostate-specific membrane antigen uptake in the distal esophagus. Both patients had hiatus herniation on gastroscopy, and esophageal biopsies revealed acute and chronic inflammation in both patients and a benign hyperplastic polyp in one of the patients. Recently, reports have demonstrated that inflammation can cause false-positive findings on Ga-prostate-specific membrane antigen PET/CT, and these cases present this phenomeno...

Schmorl's Node: Confusion Still Persists in 68Ga-Prostate-Specific Membrane Antigen Ligand PET/CT.

Ga-prostate-specific membrane antigen (PSMA) ligand PET/CT is commonly believed to be prostate specific as the name itself suggests. However, PSMA-expressing nonprostatic cancers as well as benign lesions are continuously being added to the list. We reported PSMA-expressing Schmorl's node in L1 vertebra of a 74-year-old man with prostate cancer. Prostate-specific membrane antigen expression in the vertebral lesion raised a metastatic suspicion. However, on analysis of previous CT scan done 2 years before, t...

Mediastinal Duplication Cyst on 99mTc Pertechnetate Scan.

A 3-year-old boy presented with intermittent abdominal pain, melena, and anemia since 2 months. Upper gastrointestinal endoscopy did not reveal any significant abnormality. The child was then referred for Tc-pertechnetate scan to rule out the presence of ectopic functioning gastric mucosa. Tc-pertechnetate scan revealed abnormal tracer accumulation in the thoracic region, which persisted in the delayed images, suspicious for being ectopic gastric mucosa. Subsequently, ultrasound and contrast-enhanced CT (CE...

More accurate than MRI measurement of tumor size in breast cancer by using the peri-tumoral halo uptake layer method of the F-FDG PET/CT scan.

To evaluate the reliability of a method using the peri-tumoral halo layer (PHL) for assessing tumor size in breast cancer patients on the fluorine-18-fluorodeoxy glucose positron emission tomography/computed tomography (F-FDG PET/CT) scan compared to MRI and pathology.

Gemstone spectral imaging in lung cancer: A preliminary study.

The present study aimed to evaluate the application of gemstone spectral imaging (GSI) for multi-parameter quantitative measurement in lung cancer.The study retrospectively enrolled 30 patients with lung cancer who underwent chest contrast enhanced CT scan with GSI mode. The GSI viewer was used for image display and data analysis. Optimal energy value, CT values at 40 keV, 70 keV and optimal energy level, spectral curve slope, effective atomic number (Zeff), iodine concentration (IC), and water concentratio...

Rapid Assessment of the Neonate With Sonography (RANS) Scan.

The use of point-of-care sonography in clinical settings such as emergency medicine and intensive care units has increased, but adoption in neonatology has been slow. Unlike the focused assessment with sonography for trauma scan used in adults, a quick bedside scan to rapidly evaluate an acutely deteriorating neonate does not exist. The objective of our article is to introduce a focused bedside ultrasound scan that is easy to learn, rapidly performed, and relatively inexpensive.© 2018 by the American Insti...

Radioligand therapy of metastatic castration-resistant prostate cancer: current approaches.

Prostate Cancer is the forth most common type of cancer. Prostate-specific membrane antigen (PSMA) is anchored in the cell membrane of prostate epithelial cells. PSMA is highly expressed on prostate epithelial cells and strongly up-regulated in prostate cancer. Therefore it is an appropriate target for diagnostic and therapy of prostate cancer and its metastases. This article discusses several articles on radionuclide treatments in prostate cancer and the results on PSMA therapy with either beta or alpha em...

Impact of long-term androgen deprivation therapy on PSMA ligand PET/CT in patients with castration-sensitive prostate cancer.

Since the introduction of PSMA PET/CT with Ga-PSMA-11, this modality for imaging prostate cancer (PC) has spread worldwide. Preclinical studies have demonstrated that short-term androgen deprivation therapy (ADT) can significantly increase PSMA expression on PC cells. Additionally, retrospective clinical data in large patient cohorts suggest a positive association between ongoing ADT and a pathological PSMA PET/CT scan. The present evaluation was conducted to further analyse the influence of long-term ADT o...

The Role of Testosterone Therapy in the Setting of Prostate Cancer.

The role of testosterone in the development of prostate cancer and the safety of testosterone therapy (TTh) after prostate cancer treatment, or in the setting of active surveillance, remains controversial. There are many concerns about using TTh in men, particularly those with a history of prostate cancer, ranging from a possible increased risk of cardiovascular disease to cancer progression or recurrence. With many prostate cancer patients living longer, and hypogonadism having significant morbidity, much ...

Modelling human prostate cancer: Rat models.

Prostate cancer is the second most common cancer in men, affecting approximately 1.1 million men worldwide. In this way, the study of prostate cancer biopathology and the study of new potential therapies is of paramount importance. Several rat models were developed over the years to study prostate cancer, namely spontaneous models, chemically-induced models, implantation of cancer cell lines and genetically-engineered models. This manuscript aimed to provide the readers with an overview of the rat models of...

68Ga-Labeled Prostate-Specific Membrane Antigen Uptake in Pheochromocytoma: An Incidental Finding in PET/CT Scan.

We report a case of adenocarcinoma prostate treated previously with radical prostatectomy and hormonal therapy who underwent Ga-labeled prostate-specific membrane antigen PET/CT for recurrence evaluation. In addition to radiotracer uptake in the prostate bed, unusual intense prostate-specific membrane antigen uptake was also noted in the left adrenal gland. With a clinical suspicion of pheochromocytoma, Ga-DOTANOC PET/CT was done, which revealed tracer-avid left adrenal lesion.

Intraoral scan bodies in implant dentistry: A systematic review.

Intraoral scan body (ISB) design is highly variable and its role in the digital workflow and accuracy of digital impressions is not well understood.

Lumbar Osteophyte Avid on 68Ga-Prostate-Specific Membrane Antigen PET/CT.

A 75-year-old man with recently diagnosed high-risk prostate cancer was referred for primary staging with Ga-prostate-specific membrane antigen (PSMA) PET/CT. The scan revealed intense Ga-PSMA uptake in a lumbar osteophyte on the right side of level L2/L3, whereas several other spinal osteophytes showed no Ga-PSMA uptake. MRI findings in the L3 vertebra was consistent with a benign Modic type 1 lesion, but MRI showed no signs of malignancy in the osteophyte with high Ga-PMSA uptake. This case presents an os...

A Novel Method to Extend a Partial-Body CT for the Reconstruction of Dose to Organs beyond the Scan Range.

Epidemiological investigation is an important approach to assessing the risk of late effects after radiotherapy, and organ dosimetry is a crucial part of such analysis. Computed tomography (CT) images, if available, can be a valuable resource for individualizing the dosimetry, because they describe the specific anatomy of the patient. However, CT images acquired for radiation treatment planning purposes cover only a portion of the body near the target volume, whereas for epidemiology, the interest lies in t...

Association of zinc level and polymorphism in MMP-7 gene with prostate cancer in Polish population.

Prostate cancer is one of the most commonly diagnosed malignancies among men in Western populations. Evidence reported in the literature suggests that zinc may be related to prostate cancer. In this study we evaluated the association of serum zinc levels and polymorphisms in genes encoding zinc-dependent proteins with prostate cancer in Poland.
