Resumen

Technetium 99m sestamibi ayuda a distinguir los oncocitomas renales benignos de los carcinomas cromófobos de células renales malignas. Esta técnica de imagen se puede integrar en algoritmos de diagnóstico para masas renales incidentales, lo que podría reducir las biopsias innecesarias.

Área de la Ciencia:

En el campo de la oncología
La medicina nuclear
Radiología

Sus antecedentes:

Los oncocitomas renales y los carcinomas cromofóbicos de células renales (CRCC) presentan características de imagen similares en la TC/ RM, lo que complica el diagnóstico.
La diferenciación tradicional se basa en la biopsia invasiva, lo que plantea riesgos y el potencial de tratamiento excesivo.
Los tumores oncocíticos/cromofóbicos híbridos difuminan aún más las líneas entre las lesiones renales benignas y malignas.

Urinary Tract Calculi III: Medical Management

The diagnosis of renal calculi involves several imaging techniques, including non-contrast CT scans and ultrasound. These methods help visualize kidney stones, assess their size and location, and detect possible obstructions. Additionally, Measuring urine pH is useful for diagnosing specific stone types, such as struvite (alkaline pH) and uric acid stones (acidic pH). Cystine stones are primarily linked to cystinuria, a genetic condition. A urinalysis helps detect blood in the urine (hematuria)...

Imaging Studies III: Computed Tomography

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...
