Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological Investigation III: Pulmonary Angiogram and PET Scan

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...

Imaging Studies for Cardiovascular System III: X-Ray

Imaging Studies for Cardiovascular System III: X-Ray

The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Radiological Investigation I: X-ray and CT

Radiological Investigation I: X-ray and CT

Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...

Area of Science:

Radiation Oncology
Medical Imaging
Cancer Treatment

Background:

Image-guided radiation therapy (IGRT) utilizes advanced imaging to enhance radiation delivery accuracy.
Previous guidelines were established in 2019, necessitating an update due to field advancements.

Purpose of the Study:

To revise and update the practice parameter for Image-Guided Radiation Therapy (IGRT).
To provide comprehensive guidance for the clinical application of IGRT.

Main Methods:

Development followed the established ACR Practice Parameters and Technical Standards process.
Collaboration between the American College of Radiology (ACR) and the American Radium Society (ARS).

Main Results:

The updated parameter covers personnel qualifications, clinical implementation, documentation, quality control, safety, and patient education.
Enhanced clarity on documentation requirements, imaging data interpretation, and system interactions in IGRT.

Conclusions:

The practice parameter supports practitioners in the clinical use of IGRT.
IGRT should augment existing quality assurance processes.
Practitioners must understand IGRT's strengths and limitations in this evolving field.
