Hepatitis is known to induce severe liver diseases. The evaluation of the severity of liver cirrhosis is very important for the selection of appropriate treatment plan and the monitoring of patient response to treatment, accurate staging of liver fibrosis is critical because it determines the indication of antiviral treatment and prognosis of patients with chronic viral hepatitis, DWI is a particularly appealing method for the diagnosis of liver fibrosis because it is easy to i...
Diffusion-weighted sequences have been routinely performed for years to study the pelvis. They have been so far mainly qualitatively interpreted, that is to say as the absence or presence of an hypersignal at a high b value. The quantitative analysis involves placing the region of interest (ROI) on the apparent diffusion coefficient (ADC) map. The manual placement is very operator dependent, and does not reflect the entirety of the studied mass. In all fields of Magnetic Reson...
RATIONALE: Gathering information about the Gleason score, prostate-specific antigen (PSA) level, and cancer stage from patients who have undergone radiation therapy for prostate cancer may help doctors predict how patients respond to treatment and help plan the best treatment. PURPOSE: This clinical trial is studying the Gleason score, PSA level, and cancer stage in predicting outcome in patients who have undergone radiation therapy for localized prostate cancer.
Multiparametric magnetic resonance imaging (mpMRI) of the prostate combines T2-weighted imaging, diffusion-weighted imaging and dynamic contrast-enhanced imaging. Correlation with radical prostatectomy specimens has demonstrated that mpMRI has excellent sensitivity in detecting prostate cancers (PCa) with a Gleason score ≥7 and cancers with a Gleason 6 and a volume ≥0.5 cc. Nevertheless, its specificity is poor and there is large overlapping between the appearances of benig...
Prostate Cancer (PCa) is the most common male cancer in Denmark and the number is increasing. Annually, about 1,600 men are referred to the Department of Urology, Herlev Gentofte Hospital, due to elevated PSA (Prostate Specific Antigen) or clinical symptoms suspicious of PCa. In approximately 50% of these patients, PCa is diagnosed based on histopathological findings in tissue obtained from transrectal ultrasound biopsy (TRUS-bx). The TRUS-bx is taken from 10 standard zones in ...
Prostate specific membrane antigen (PSMA) is a unique membrane bound glycoprotein, which is overexpressed manifold on prostate cancer cells and is well-characterized as an imaging biomarker of prostate cancer. Positron emission tomography / computer tomography (PET/CT) is a nuclear medicine procedure based on the measurement of positron emission from radiolabeled tracer molecules. 18F-DCFPyL is a tracer for prostate cancer PET imaging which binds to PSMA. The strength of functi...
In 22% of patients with elevated Prostate-specific antigen (PSA) MRI guided biopsy will not detect significant prostate cancer (PCA) (defined as either: Gleason score (GS) ≥ 3+4 or tertiary pattern 5, or final stage ≥ pT3a and/or pN1). Therefore this study evaluates the ability of [68Ga]PSMA PET/MRI to detect and localize significant primary PCA to accurately direct prostate needle biopsy using the Gleason score from the histology of the core biopsies as standard of truth.
We aim to analyze whether the "liquid biopsy" model could increase the specificity of detecting men with an aggressive (defined as Gleason score ≥ 7) prostate cancer and thereby reduce the proportion of men who undergo prostate biopsy, while at the same time maintaining the same sensitivity to detect aggressive prostate cancer as the PSA test alone. Using blood and urine biomarkers together with an algorithm, which incorporates the clinical data, we aim to identify patients w...
This is a pilot cancer imaging study investigating change in the apparent diffusion coefficient (ADC) at a single time point post-transplantation in patients. The treatment is bone marrow transplant as per standard patient care, without change for trial purposes. Its main aim is to evaluate the engraftment of bone marrow after transplantation performing functional Magnetic Resonance Imaging (MRI) of the lumbar spine and pelvis at baseline and after 2-3 weeks after the transpla...

To evaluate the absence of biopsy detectable Gleason grade 4 or 5 prostate cancer tumors anywhere in the prostate gland on 12-month, post-treatment biopsy following TOOKAD® Soluble-VTP in men with prostate cancer Gleason score 7(3+4).
- The goal of this study is to determine the feasibility of the diffusion weighted Magnetic Resonance Imaging in the evaluation of the treatment response in patients with malignant lymphoma. - The investigator's objective is to compare the changes of mean Apparent Diffusion Coefficient value of the tumor with the changes of maximum Standardized Uptake Value of the tumor in positron Emission Tomography Computed Tomography in both pre and post ...
This is a study of men who have undergone a standard 10 or more core biopsy for detection of prostate cancer and determined to have prostate cancer Gleason score ≤ 7 (low to moderate risk 2-7). Of these men, one arm of a two arm randomized group will be administered a treatment regime of Dutasteride versus the control group who receive standard of care, prior to mapping biopsy. This proposal aims at studying the apparent effect of the use of Dutasteride (3 months) on initial ...
Prostate cancer is the second leading cause of cancer death in North American men older than 50 years. Prostate specific membrane antigen (PSMA) is a unique membrane bound glycoprotein, which is overexpressed manifold on prostate cancer cells and is well-characterized as an imaging biomarker of prostate cancer. Positron emission tomography / computer tomography (PET/CT) is a nuclear medicine procedure based on the measurement of positron emission from radiolabeled tracer molecu...
This randomized trial will compare the safety and efficacy of TPM versus TRUS biopsies performed in the outpatient setting.
