Summary
X-ray computed tomography (CT) effectively detects large liver cancers, but identifying early-stage hepatocellular carcinoma (HCC) remains challenging. Further research is needed to improve CT
Area of Science:
- Radiology
- Medical Imaging
- Oncology
Background:
- Computed tomography (CT) is extensively studied for liver lesion detection.
- Technological progress and understanding of tumor pathophysiology have improved detection of large hepatocellular carcinomas (HCCs).
Purpose of the Study:
- To review the imaging appearances of HCC on CT.
- To discuss the sensitivity and specificity of CT for screening cirrhotic patients for HCC.
Main Methods:
- Review of imaging findings of HCC on CT scans.
- Analysis of diagnostic performance data for CT in HCC screening.
Main Results:
- CT effectively detects and characterizes large HCCs.
- Detection and characterization of early and small HCC lesions using CT remain difficult.
Conclusions:
- While CT excels at identifying advanced HCC, its efficacy in detecting early-stage disease in cirrhotic patients requires further investigation.
- Improved CT techniques and interpretation may enhance early HCC detection in high-risk populations.

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...

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...

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...
