We present pyOsiriX, a plugin built for the already popular dicom viewer OsiriX that provides users the ability to extend the functionality of OsiriX through simple Python scripts. This approach allows users to integrate the many cutting-edge scientific/image-processing libraries created for Python into a powerful DICOM visualisation package that is intuitive to use and already familiar to many clinical researchers.
We wished to compare the efficacy of ultrasound versus intravenous contrast-enhanced computed tomography (CT) for detecting recurrent renal cell carcinoma (RCC) by identifying patients presenting with such tumor burden and to evaluate the utility of these imaging modalities in these circumstances.
AIM - To develop a nomogram from clinical and computed tomography (CT) data for pre-treatment identification of indolent renal cortical tumours.
PATIENT AND METHODS - A total of 1201 consecutive patients underwent dedicated contrast-enhanced CT prior to nephrectomy for a renal cortical tumour between January 2000 and July 2011.
Renal cell carcinoma (RCC) is the seventh most common histological type of cancer in the Western world and has shown a sustained increase in its prevalence. The histological classification of RCCs is of utmost importance, considering the significant prognostic and therapeutic implications of its histological subtypes.
To investigate the reproducibility and interobserver agreement for R.E.N.A.L. nephrometry scoring system.
Two independent radiologists retrospectively analyzed 46 consecutive patients with renal masses, between 2008 and 2012, using the R.
Germ cell tumors (GCTs) are the most common tumors of the testis and arise from germinal epithelium cells in the seminiferous tubules. All GCTs show malignant behavior and frequently metastasize. The diagnosis of GCTs depends on the clinical manifestations, laboratory parameters, preoperative imaging features, and tissue biomarkers.
A method to discriminate different types of renal cell carcinoma (RCC) was developed using attenuation values observed in multiphasic contrast-enhanced CT. This work evaluates the sensitivity of this RCC discrimination task at different CT radiation dose levels.
To assess subcutaneous adipose tissue characteristics by computed tomography (CT) as potential imaging biomarkers predictive of biochemical recurrence in men with high-risk prostate cancer receiving radiotherapy (RT).
As a crucial step in accessing the kidney in several minimally invasive interventions, percutaneous renal access (PRA) practicality and safety may be improved through the fusion of computed tomography (CT) and ultrasound (US) data.
Upper tract urothelial carcinoma (UTUC) is a relatively uncommon but aggressive genitourinary malignancy for which multi-phase contrast-enhanced computed tomography (CT) plays an important role in evaluation and staging.
The aim of the study is to report the reliability of computed tomography urography (CTU) and ureteroscopy (URS) in the diagnosis and management of UTUC.
From 2015 to 11/2018, we prospectively collected and retrospectively analyzed 244 cases of URS with available preoperative CTU.
Bladder cancer (BC) is the most common cancer of the urinary tract in the United States. Imaging plays a significant role in the management of patients with BC, including the locoregional staging and evaluation for distant metastatic disease, which cannot be assessed at the time of cystoscopy and biopsy/resection.
We map out a typical prostate cancer care pathway through discussion of updates on modern imaging. Multiparametric MRI (mpMRI) is the most sensitive and specific imaging tool for diagnosis and local staging, transrectal ultrasound remains the most widely used technique for prostate biopsy guidance, CT and bone scan are useful in initial staging and recurrence detection.
Preliminary results have demonstrated that prostate-specific membrane antigen (PSMA) is highly expressed on the cell surface of the microvasculature of several solid tumors, including renal cell carcinoma (RCC).
Recent reports support the use of renal ultrasonography (US) as the initial imaging study for the evaluation of patients with suspected renal colic. Urologists, however, often advocate for computed tomography (CT) to better define stone size and location, especially prior to proceeding with endourologic intervention.
To determine the diagnostic performance of ultrasound for diagnosing ureteral calculi in children using a clinical effectiveness approach.
Billing records and imaging reports were used to identify children (≤ 18 years old) evaluated for suspected urolithiasis using ultrasound between March 2012 and March 2017.
Bladder cancer can spread from the sub-peritoneal space superior and posterolateral to the peritoneal cavity via the peritoneal lining. The aim of this study was to improve the identification of peritoneal spread from bladder urothelial carcinoma based on computed tomography (CT) scans.
Malignant kidney neoplasms are the most frequently encountered solid kidney masses. Although renal cell carcinoma is the major renal malignancy, other solid malignant renal masses should be considered in the differential diagnosis of solid renal masses that do not contain a macroscopic fatty component.
This study is aimed to evaluate the iodine concentration in the lipid-poor portion of the renal mass as a potential tool for the differentiation between angiomyolipoma (AML) and renal cell carcinoma (RCC).
To evaluate the utility of virtual cystoscopy (VC) performed with CT urography in patients being studied under gross hematuria or patients being followed-up after a previous bladder cancer and compare the results with those obtained with gold standard technique (optical cystoscopy).
