Contrast-induced nephropathy (CIN) is a purported form of kidney damage in which there has been recent exposure to medical imaging contrast material without another clear cause for the acute kidney injury. Despite extensive speculation, the actual occurrence of contrast-induced nephropathy has not been demonstrated in the literature. [1]
Kidney infarction: CT scan of the abdomen showing partial infarct of the left kidney. Specialty: Nephrology: Symptoms: Abdominal pain, nausea, vomiting, and fever. [1] Complications: Acute kidney injury and chronic kidney disease. [1] Causes: Cardioembolic disease, renal artery injury, and hypercoagulable state. [1] Diagnostic method

[ 12 ] [ 13 ] [ 14 ] The use of CTA in people with kidney failure , kidney disease or long-standing severe diabetes should be weighed carefully as the use of IV iodine contrast ...
AKI - the other main type of kidney disease - can be caused by dehydration, blood loss, urinary tract obstructions such as kidney stones or blood clots, low blood pressure, or heart disease. It ...
The kidney function can also be assessed with medical imaging. Some forms of imaging, such as kidney ultrasound or CT scans, may assess kidney function by indicating chronic disease that can impact function, by showing a small or shrivelled kidney. [citation needed].
Segmental hypoplasia or Ask-Upmark kidney is a rare renal disease where a part of the kidney has undergone hypoplasia. The number of renal lobes is reduced, and the kidney size is less than two standard deviations from the average, with the weight often being over 50g in adults and 12–25g in children.
Polycystic kidney disease can be ascertained via a CT scan of abdomen, as well as an MRI and ultrasound of the same area. [23] A physical exam/test can reveal enlarged liver, heart murmurs and elevated blood pressure. [1]
Causes of pneumonia in the elderly. Pneumonia can be caused by a buildup of bacteria, viruses, or fungi in the lungs. There are several types of bacteria that can cause pneumonia, some typical and ...
