Summary
Physicians frequently order computed tomography (CT) scans to rapidly diagnose conditions. Less experienced doctors may order CT scans due to litigation fears, and some are less likely to discuss radiation risks with patients.
Area of Science:
- Radiology and Imaging
- Medical Decision-Making
- Physician Behavior
Background:
- Computed tomography (CT) scans are widely used diagnostic tools.
- Concerns exist regarding radiation exposure from CT scans.
- Understanding physician decision-making for CT ordering is crucial.
Purpose of the Study:
- To survey physician attitudes, knowledge, and behavior regarding CT radiation exposure.
- To identify factors influencing the decision to order CT scans.
Main Methods:
- An electronic survey with 16 questions was distributed.
- The survey targeted 350 physicians at a large medical center.
Main Results:
- The primary driver for ordering CT scans was the need for rapid diagnosis (85%-99%).
- Fear of litigation significantly influenced CT ordering in less experienced physicians (OR=2.3).
- Residents and primary care physicians were less likely to discuss CT risks/benefits compared to experienced physicians (OR=4.0).
Conclusions:
- Diagnostic utility and speed are key factors in CT ordering.
- Physician experience level impacts CT ordering decisions and patient communication.
- Further education on radiation risk and benefit communication may be warranted for certain physician groups.

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...

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...
01:28Imaging Studies for Cardiovascular System V: CT
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...
01:24X-ray Imaging
German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with X-rays, and by 1900, X-ray was widely...
