Emphysematous cystitis is often indicated in patients who have air in the urine. [6] In some cases, emphysematous cystitis can cause thickening of the bladder wall. [ 7 ] Clinical subcutaneous emphysema is a rare complication of emphysematous cystitis that has a poor prognosis.
CT scan of subcutaneous emphysema. Subcutaneous emphysema is found in the deepest layer of the skin. Emphysematous cystitis is a condition of gas in the bladder wall. On occasion this may give rise to secondary subcutaneous emphysema which has a poor prognosis. [11]
A gas-producing UTI (emphysematous cystitis: rare). Emphysematous pyelonephritis. Male scuba divers utilizing condom catheters or female divers using a She-p external catching device for their dry suits are also susceptible to pneumaturia. [1]
CT scan of bullous emphysema. When the subpleural bullae are significant, the emphysema is called bullous emphysema. Bullae can become extensive and combine to form giant bullae. These can be large enough to take up a third of a hemithorax, compress the lung parenchyma, and cause displacement.
A computed tomography urography (CT urography or CT urogram) is a computed tomography scan that examines the urinary tract after contrast dye is injected into a vein. [1]In a CT urogram, the contrast agent is through a cannula into a vein, allowed to be cleared by the kidneys and excreted through the urinary tract as part of the urine.
Low-dose high-resolution (1.25 mm) chest CT. HRCT is performed using a conventional CT scanner. However, imaging parameters are chosen so as to maximize spatial resolution: [1] a narrow slice width is used (usually 1–2 mm), a high spatial resolution image reconstruction algorithm is used, field of view is minimized, so as to minimize the size of each pixel, and other scan factors (e.g. focal ...
CT scan or kidney ultrasonography is useful in the diagnosis of xanthogranulomatous pyelonephritis; serial imaging may be useful for differentiating this condition from kidney cancer. [10] Acute pyelonephritis with increased cortical echogenicity and blurred delineation of the upper pole [20]
MinIP is mainly used to diagnose lung diseases with computed tomography scans where the attenuation values are reduced (for example traction bronchectasis and emphysema). [3] Another application is for assessing the bile tree and pancreatic duct which compared to the surrounding tissue is hypoattenuating (especially after intravenous contrast ...
