Imaging Studies for Cardiovascular System V: CT01:28

Imaging Studies for Cardiovascular System V: CT

144
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...

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...

Imaging Studies for Cardiovascular System IV: CMRI

210
Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

Radiological Investigation I: X-ray and CT

824
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...

Summary
This summary is machine-generated.

Thirteen percent of sinus CT scans were performed despite recent head imaging that adequately evaluated the sinuses. Educating providers and radiologists can reduce these unnecessary sinus CTs, saving costs and radiation exposure.

Area of Science:

  • Radiology
  • Medical Imaging
  • Otolaryngology

Background:

  • Sinus CT scans are overutilized, leading to increased costs and radiation exposure.
  • Recent head imaging may adequately evaluate sinuses, making repeat sinus CTs unnecessary.

Purpose of the Study:

  • To assess the frequency of sinus CT scans performed after recent head imaging.
  • To identify opportunities to reduce unnecessary sinus CT utilization.

Main Methods:

  • Retrospective review of 735 sinus CT scans from an academic medical center's PACS database in 2017.
  • Exclusion of scans for trauma, tumor, operative evaluation, or acute infections other than sinusitis.
  • Identification of scans with concurrent or prior (within 4 weeks) head imaging.

Main Results:

  • 13% of sinus CT scans (19 same-day, 30 prior) were performed with recent head imaging.
  • Residents ordered the majority of these potentially redundant sinus CTs (84% same-day, 63% prior).
  • Sinuses were mentioned in all head CT reports but only 2/12 brain MRI reports.

Conclusions:

  • A significant proportion of sinus CTs are preceded by recent head imaging.
  • Targeted education for referring providers and radiologists can decrease unnecessary sinus CTs.
  • Improved communication and reporting on sinus findings in head imaging can optimize resource utilization.
