To investigate efficacy of a rectal retractor (RR) on rectal dose during image-guided dose-escalated prostate three-dimensional conformal radiotherapy (3DCRT).
The purpose of this research was to study the outcome of brain metastases in a cohort of patients undergoing a second course of stereotactic image-guided robotic radiosurgery, and to identify predictors corelated with survival.
Image-guided navigation has existed for nearly 3 decades, but its adoption to craniofacial surgery has been slow. A systematic review of the literature was performed to assess the current status of navigation in craniofacial surgery.
Near infrared (NIR) fluorescence imaging is an emerging modality that can enable real-time image-guided surgery. Indocyanine green (ICG) is an FDA approved, inexpensive, and widely available NIR dye. We hypothesized that axillary lymphatic mapping with ICG is equivalent to lymphatic mapping with technetium 99m (Tc) in breast cancer patients.
Robotic technologies have been used in the neurosurgical operating rooms for the last 30 yr. They have been adopted for several stereotactic applications and, particularly, image-guided biopsy of intracranial lesions which are not amenable for open surgical resection.
In image-guided laparoscopy optical tracking is commonly employed, but electromagnetic (EM) systems have been proposed in the literature. In this paper, we provide a thorough comparison of EM and optical tracking systems for use in image-guided laparoscopic surgery and a feasibility study of a combined, EM tracked laparoscope and laparoscopic ultrasound (LUS) image-guidance system.
To evaluate the incidence and predictors for late toxicity and tumor outcome after hypofractionated radiotherapy using three different image-guided radiotherapy (IGRT) systems (hypo-IGRT) compared with conventional fractionation without image guidance (non-IGRT).
With increasing incorporation of MRI in radiotherapy, we investigate two MRI sequences for prostate delineation in radiographer-led image guidance.
This study aimed to investigate the feasibility of an automatic marker-free patient-to-image spatial registration method based on the 4-points congruent sets (4PCS) and iterative closest point (ICP) algorithm for the image-guided neurosurgery system (IGNS).
Prior randomized studies have shown a survival benefit using combined androgen deprivation therapy (ADT) and radiation therapy for intermediate-risk prostate cancer. However, these studies either used low doses of radiation (66.6 Gy to isocenter) or imaged guidance was not available. This study reports the initial differences for high dose image guided radiation with or without ADT.
Conventional imaging cannot definitively detect nodal metastases from prostate cancer (PCa). We histologically validated 11-carbon-Acetate (C-Acetate) PET/CT for identifying nodal metastases, examining PCa factors that influence detection rates.
We developed a novel approach combined with 3D Image Analyzer and infrared thoracoscopy for pulmonary sublobar resection. The purpose of this study was to investigate the feasibility of this procedure.
Peritoneal carcinomatosis in prostate cancer is extremely rare and has been described in only few cases with high PSA level, androgen deprivation, or in symptomatic patients. To date, 2 cases of Ga-PSMA PET positive peritoneal metastases have been reported. We report a case of urachus metastases showed on Ga-PSMA PET/CT performed for biochemical recurrence with a very low PSA level at 0.50 ng/mL.
5-ALA-based fluorescence-guided surgery has been shown to be a safe and effective method to improve intraoperative visualization and resection of malignant gliomas. However, it remains ineffective in guiding the resection of lower-grade, non-enhancing, and deep-seated tumors, mainly because these tumors do not produce detectable fluorescence with conventional visualization technologies, namely, wide-field (WF) surgical microscopy.
In this study, we hypothesized a disposable low-cost needle clip with a specially designed electromagnetic (EM) tracking sensor. It could be mounted onto 16- to 22-gauge needles, allowing the tip of the needle to be tracked in CT or US image-guided procedures using the Aurora EM tracking system.
To evaluate the effectiveness of an antibiotic regimen for prostate biopsy by analyzing patients who were hospitalized because of complications after transrectal ultrasound-guided prostate biopsy.
This study proposes a method to analyze surgical performance by modeling, aligning, and comparing surgical processes. This method is intended to serve as a means to support the enhancement of surgical skills for endoscopic sinus surgeries (ESSs). We focus on surgical navigation systems used in image-guided ESSs and aim to construct a comparative analysis method for surgical processes based on the information about the surgical instruments motion obtained from the navigation system.
Metastases-yield and Prostate-specific Antigen Kinetics Following Salvage Lymph Node Dissection for Prostate Cancer: A Comparison Between Conventional Surgical Approach and Prostate-specific Membrane Antigen-radioguided Surgery.
The first results on Technetium prostate-specific membrane antigen-radioguided surgery (Tc-PSMA- RGS) showed promising outcome. Here, we sought to evaluate if this targeted molecular surgical approach might be more effective than conventional salvage lymph node dissection (sLND). We prospectively analysed 42 consecutive patients who underwent sLND based on preoperative Gallium (Ga)-PSMA-positron emission tomography (PET) imaging between 2015 and 2018. In 29 patients, the dissection field was based solely Ga...
A 69-year-old man with newly diagnosed prostate cancer PSA 274 ng/mL, Gleason 4+3, T-stage 3b) underwent Ga-PSMA PET/CT for staging with follow-up scans 6 and 13 weeks after androgen deprivation therapy (ADT) initiation. Six weeks after ADT initiation, lymph node metastases observed at staging showed metabolic and radiological regression, whereas the skeleton showed increased PSMA uptake in existing bone metastases and several new PSMA-avid lesions. Skeletal PSMA uptake decreased after 13 weeks of ADT, and ...
Lymphatic malformation is a congenital lymphatic disorder. Although a few lymphangiographic and lymphoscintigraphic studies of lymphatic malformation exist, its lymphatic flow has not been fully assessed, and a classification system has not yet been established. However, indocyanine green lymphography has been developed to safely provide a fine assessment of lymph flow in the treatment of lymphedema. In addition, indocyanine green lymphography has been shown to be helpful in detecting the lymphatic malforma...
In the United Kingdom fiducial marker IGRT is the second most common verification method employed in radical prostate radiotherapy yet little evidence exists to support centres introducing or developing this practice. We developed a survey to elicit current fiducial marker practices adopted in the UK, to recommend standardisation of practice.
To evaluate the accuracy of commercially available hybrid deformable image registration (DIR) algorithms when using planning CT (pCT) and daily cone-beam computed tomography (CBCT) in radiation therapy for prostate cancer. The hybrid DIR algorithms in RayStation and MIM Maestro were evaluated. Contours of the prostate, bladder, rectum, and seminal vesicles (SVs) were used as region-of-interest (ROIs) to guide image deformation in the hybrid DIR and to compare the DIR accuracy. To evaluate robustness of the ...
Image-guided microwave ablation (MWA) is a technically demanding procedure, involving advanced visual-spatial perception skills. This study sought to create and evaluate a low-cost model and training curriculum for open ultrasound-guided liver tumor MWA.
Surgery of advanced tumors and lymph nodes in the pelvis can be challenging due to the narrow pelvic space and vital surrounding structures. This study explores the application of a novel electromagnetic navigation system to guide pelvic surgery.
