Imaging Studies III: Computed Tomography

78
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...

Imaging Studies VII: Vascular Imaging

86
DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Radiological Investigation II: MRI and Ventilation Perfusion Scan

243
Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Imaging Studies IV: Magnetic Resonance Imaging

67
Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

Area of Science:

  • Vascular Surgery
  • Hepatology
  • Radiology

Background:

  • Abernethy malformation, a congenital extrahepatic portosystemic venous shunt, is a rare portal venous system anomaly.
  • Increasing reports necessitate timely diagnosis due to potential severe clinical consequences.

Observation:

  • This report details a case of Abernethy malformation incidentally discovered in an adult transgender individual.
  • The anomaly presented without overt symptoms.

Findings:

  • Echocardiographic, computed tomography (CT), and magnetic resonance imaging (MRI) were utilized for diagnosis.
  • Imaging findings confirmed the presence of the congenital extrahepatic portosystemic venous shunt.

Implications:

  • Early diagnosis of Abernethy malformation is crucial to prevent serious health issues like hepatic carcinoma and pulmonary hypertension.
  • This case broadens the understanding of Abernethy malformation presentation and diagnosis across diverse patient demographics.
