R.E.N.A.L. Nephrometry Score

The R.E.N.A.L. nephrometry score quantifies renal tumor size, location, and depth on CT/MRI to guide partial vs. radical nephrectomy decisions and predict surgical complexity.

Renal Artery Doppler Evaluation

Renal artery duplex ultrasound criteria for renal artery stenosis: PSV, renal-aortic ratio, acceleration time/index, and resistive index thresholds, with imaging findings and pitfalls.

Ovarian-Adnexal Reporting and Data System Ultrasound – O-RADS US

What is the O-RADS Ultrasound scoring system? O-RADS US (Ovarian-Adnexal Reporting and Data System — Ultrasound) is a 5-category risk stratification system developed by the American College of Radiology (ACR) to standardize the reporting of ovarian and adnexal lesions on ultrasound. It assigns each lesion a score from 1 to 5 based on morphological features…
