“…In another study, it mentioned that two small accessory renal arteries were missed by all reviewers. Those arteries were diminutive and were thought to be insignificant by the surgeons [7]. The accuracy of MDCT was 98.2%, however, other studies got higher results, as in this study, whereas CTA had an accuracy of 100% for diagnosing the number of renal arteries on the side of nephrectomy [5].…”

“…Several reports have shown the accuracy of one-channel CT angiography in establishing the presence of variations or anomalies of renal arteries and veins. The reported accuracy of one-channel CT angiography in detecting accessory arteries, early branching, and renal venous anatomy is in the range of 78-98%, 89-99%, and 90-99%, respectively [7].…”

Multi Detector Computed Tomography Angiography (MDCTA) provides a fast, non-invasive modality for the evaluation of the renal vascular pedicle. CTA can reliably and accurately depict the renal arteries and veins and approaches conventional angiography in the assessment of most vascular abnormalities. Knowledge of the variations in renal vascular anatomy is important before laparoscopic donor or partial nephrectomy and vascular reconstruction for renal artery stenosis or abdominal aortic aneurysm. Objective: To illustrate the diagnostic accuracy of MDCT for evaluation of renal vasculature anatomy. Design: An analytic, comparative study. Subjects: fifty six patients including 43 living renal donors, 13 hypertension and abdominal pain (27 men and 29 women, mean age 39.5 years) were examined from January 2008 to September 2010 in Radiology department, Farwania hospital Kuwait. Gold standard was the operative data, conventional angiography or DSA. Main outcome: The value of MDCT in assessment of renal vascular anomalies. Results: Renal vascular anatomical variants included multiple arteries (21.4%), multiple veins (7.1%), early arterial bifurcation (8.9%), late venous confluence (7.1%), circum-aortic renal veins (7.1%) and retro-aortic vein (3.6%). The sensitivity and specificity of multiple arterial anomalies were 91.7% and 97.7%, respectively. The sensitivity and specificity of multiple venous anomalies were 85.7% and 97.6%, respectively. Conclusion: MDCT is valuable for detection of renal vascular anomalies.

To combat the irreversible decline in renal function associated with kidney disease, it is essential to establish non‐invasive biomarkers for assessing renal microcirculation. However, the limited resolution and/or vascular sensitivity of existing diagnostic imaging techniques hinders the visualization of complex cortical vessels. Here, a 3D renal ultrafast Doppler (UFD) imaging system that uses a high ultrasound frequency (18 MHz) and ultrahigh frame rate (1 KHz per slice) to scan the entire volume of a rat's kidney in vivo is demonstrated. The system, which can visualize the full 3D renal vascular branching pyramid at a resolution of 167 µm without any contrast agent, is used to chronically and noninvasively monitor kidneys with acute kidney injury (AKI, 3 days) and diabetic kidney disease (DKD, 8 weeks). Multiparametric UFD analyses (e.g., vessel volume occupancy (VVO), fractional moving blood volume (FMBV), vessel number density (VND), and vessel tortuosity (VT)) describe rapid vascular rarefaction from AKI and long‐term vascular degeneration from DKD, while the renal pathogeneses are validated by in vitro blood serum testing and stained histopathology. This work demonstrates the potential of 3D renal UFD to offer valuable insights into assessing kidney perfusion levels for future research in diabetes and kidney transplantation.
