Computed tomography of the kidney

Computed tomography of the abdomen of calves during the first 105 days of life: III. Urinary tract and adrenal glands

“…There was considerable individual variation in the density of the renal parenchyma, but there were no differences between the kidneys of individual calves. This is in agreement with the results of CT of human kidneys, in which the parenchyma appeared relatively homogeneous and had a density of 30 to 50 HU (Sagel et al, 2002). The renal density of the calves at the last examination (27.2 HU left, 30.1 HU right) was similar to that of adult goats (18.5 to 39.5 HU).…”

Renal involvement in lymphoma: prevalence and various patterns of involvement on abdominal CT

“…The combination of its non-invasive nature and extremely high diagnostic yield ultimately makes CT an integral component of uro-radiological diagnosis. Computed tomography is the most sensitive, efficient and comprehensive examination modality for evaluation of the kidneys in patients with suspected renal lymphoma [5,9]. Intravenous contrast administration is essential for the diagnosis of renal lymphoma in the majority of patients.…”

Extraspinal Critical Findings on Lumbar Spine Imaging: What the Neuroradiologist Cannot Afford to Miss

“…25 The obstructing lesion may also be seen. 26,27 On MR imaging, the dilated renal collecting system will demonstrate fluid signal intensity with high T2 and low T1 signal-intensity characteristics (Figs 4 and 5). At times, the findings can be confirmed or better visualized on the scout images (Fig 6).…”

“…An example is displayed in Fig 4 in a patient who had multiple spinal interventions in the past, and the study was ordered in the emergency department to rule out cauda equina syndrome. 27 The renal and ureteral systems deserve thorough evaluation in lumbar spine imaging. Faced with a renal obstruction, after review of prior films, it would be advisable to recommend CT of the abdomen/pelvis (without contrast if the CT is for calculi or as part of a CT urogram if there is Hydroureteronephrosis secondary to a right ureterocele.…”
