Imaging Studies VII: Vascular Imaging

123
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 III: Pulmonary Angiogram and PET Scan

245
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Radiological Investigation II: MRI and Ventilation Perfusion Scan

299
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...

Imaging Studies for Cardiovascular System V: CT

131
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...

Area of Science:

  • Oncology
  • Radiology
  • Surgical Oncology

Background:

  • Hepatic arterial infusion (HAI) chemotherapy involves surgically implanted pumps for direct liver drug delivery.
  • This approach is utilized for primary or secondary liver cancers to enhance drug concentration in the liver.
  • HAI aims to improve treatment effectiveness by minimizing systemic toxicity.

Purpose of the Study:

  • To provide radiologists with an overview of HAI therapy.
  • To familiarize radiologists with the principles of pump placement and imaging.
  • To highlight potential complications associated with HAI devices.

Main Methods:

  • Review of HAI therapy principles and clinical applications.
  • Discussion of imaging modalities and findings related to HAI pumps.
  • Identification of potential complications and their imaging characteristics.

Main Results:

  • HAI is a valuable treatment modality in various liver cancer scenarios (adjuvant, conversion, unresectable).
  • Radiologists are integral to patient selection and management.
  • Familiarity with device placement and imaging is essential for accurate interpretation.

Conclusions:

  • Radiologists must understand HAI therapy to effectively manage patients.
