“…MR and MRA imaging can be the second choice after DUS in pediatric patients. Some conventional MR sequences, such as T1-VIBE, out-of-phase (opposed phase) T1, FSE T2WI, T2-TRUFI and T2-HASTE sequences, may be useful for the diagnosis of NCS, with the benefit of not requiring contrast media exposure [14,15]. Although MRA angiography is not associated with radiation exposure, it still requires the usage of contrast material.…”

Background/aim: The presented study aimed to evaluate the utility of magnetic resonance angiography(MRA) in the pediatric population with nutcracker syndrome. Materials and methods:Patients with suggestive clinical symptoms and laboratory findings and got the diagnosis of nutcracker syndrome with Doppler ultrasonography between January 2011-2019 were included in the study. In addition, children who had renal MRA due to hypertension were evaluated as the control group. MRA images of all patients were examined retrospectively by three radiologists at different levels of experience, and the superior mesenteric artery angle, aorta-mesenteric distance, left renal vein diameter both in the regions of aorta-mesenteric and renal hilum were recorded.Results: Forty-five patients diagnosed with nutcracker syndrome were included in the study. The mean age of patients was 12 (4-16) and 30 (67%) were female. As the control group, 25 patients with hypertension who had MRA were included and they had a mean age of 12 (1-18) and 19 (76%) were male. The mean superior mesenteric artery angle was 26.5 ° (16-73 ± 12) in the patient group and 57.8 ° (25-139, ± 33) in the control group (p <0.001); the mean aorta-mesenteric distance was 3.3 mm (1.7-6.5, ± 1.1) in the patient group and 8 mm (3.4-32, ± 5.9) in the control group (p <0.001). MRA measurements of three radiologists were consistent with each other. Conclusion:MRA imaging can be applied as an alternative diagnostic method for Doppler ultrasonography and Multidetector CT examinations by radiologists with different experience levels in pediatric patients with nutcracker syndrome.

“…Er et al assessed the value of several MRI sequences in 40 children with NCS, and compared the sequences according to anatomical depiction, measurability and pulsation artefact; T2-TRUFI (True Fast Imaging with Steady-State Free Precession) provided the best imaging quality. 14 …”

The nutcracker phenomenon, also known as left renal vein entrapment, occurs when there is extrinsic compression of the left renal vein, most often between the abdominal aorta and the superior mesenteric artery. Nutcracker syndrome refers to the constellation of clinical symptoms that may arise from the nutcracker phenomenon, typically inclusive of haematuria, flank/pelvic pain, orthostatic proteinuria and (in male patients) varicocele. We provide a short review of the nutcracker syndrome including various diagnostic and therapeutic modalities. We utilise our own experience with a patient as a case study and highlight the modern management option of endovascular stenting.

“…However, MRI can provide anatomic data similar to that obtained with CT, with similar sensitivity and specificity. 17 In addition, noncontrast-enhanced MRI with specialized sequences can be used, further decreasing the examination risk. Many clinicians prefer MRI to CT for children, specifically, to reduce the cumulative radiation risk.…”
