Computed Tomography Articles

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.

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.

Purpose: 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).
