Imaging Studies III: Computed Tomography

95
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...

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Computed Tomography

7.3K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Mitral Stenosis II: Clinical features and Diagnostic Tests

50
Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...

Area of Science:

  • Radiology
  • Oncology
  • Pathology

Background:

  • Unicentric Castleman disease (UCD) is a rare lymphoproliferative disorder.
  • Accurate preoperative assessment of UCD is crucial for surgical planning and patient management.

Purpose of the Study:

  • To correlate multidetector computed tomography (MDCT) classification of UCD with its surgical and pathologic features.
  • To evaluate the utility of MDCT in assessing tumor characteristics and guiding surgical intervention.

Main Methods:

  • Retrospective analysis of 63 UCD cases confirmed by pathology.
  • All patients underwent MDCT examinations.
  • Radiologists classified UCD based on imaging manifestations and reviewed surgical, histopathological, and imaging features.

Main Results:

  • UCD cases were classified into four imaging types (I-IV) based on mass characteristics and margins.
  • Types I and II (smooth or irregular margins) were predominantly hyaline-vascular type post-resection.
  • Type III (invasive, blurred margin) showed varied resection success and mixed pathology, while Type IV (multiple fused masses) had incomplete resection in one case (plasma cell type).

Conclusions:

  • MDCT is highly effective for detecting and diagnosing UCD.
  • MDCT-based classification reliably assesses tumor infiltration and growth patterns.
  • This classification system assists in optimizing surgical strategies for UCD.
