Summary
Cone beam computed tomography (CBCT) provides valuable cross-sectional imaging during vascular interventions. This technology aids in treatment planning and guidance, proving useful in most early applications.
Area of Science:
- Medical Imaging
- Interventional Radiology
Background:
- Cone beam computed tomography (CBCT) utilizes flat-panel detector technology for CT-like imaging.
- CBCT enables cross-sectional imaging without patient repositioning during procedures.
- It facilitates real-time soft tissue imaging for enhanced procedural management.
Purpose of the Study:
- To evaluate the utility of CBCT in vascular interventional procedures.
- To assess the impact of CBCT on treatment planning, guidance, and outcome assessment.
Main Methods:
- 24 CBCT scans were performed between December 2008 and June 2009.
- Scans were conducted using a multi-axis flat-panel angiographic unit during vascular interventions.
- Procedures included hepatic trans-arterial chemoembolisation and hepatic arterial Yttrium-90 infusion.
Main Results:
- CBCT was utilized in 24 vascular interventional procedures.
- Indications included hepatic trans-arterial chemoembolisation (10 cases), hepatic arterial Yttrium-90 infusion (9 cases), and other procedures (5 cases).
- CBCT was deemed useful in 20 out of 24 cases (83.3%).
Conclusions:
- Early experience indicates CBCT is beneficial for decision-making in select vascular interventions.
- The study highlights the potential of CBCT in interventional suites.
- Advancements in CBCT technology are expected to broaden its clinical applications.

01:10Computed Tomography
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...

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...

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...

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...

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...
