Single CT scan could diagnose heart disease

The motivation for using less Radiation Dose can be a powerful motivator.

According a report in the March 4 issue of Circulation, researchers at the Medical University of South Carolina (MUSC) developed a dual-source CT scanner technique that enables comprehensive diagnosis of heart disease based on a single CT scan.

“This technique could be the long coveted ‘one-stop-shop’ test that allows us to look at the heart vessels, heart function and heart blood flow with a single CT scan and within a single breath hold,” said U. Joseph Schoepf, MD, associate professor or radiology and cardiology, MUSC.

According to the report,

  • Comprehensive heart disease diagnosis is difficult because it requires not only a detailed view of structures like heart valves and blood vessels but also blood flow evaluation.
  • Clinicians at most cardiovascular centers traditionally have relied on several imaging modalities, such as cardiac catheterization, nuclear medicine or magnetic resonance.
  • While CT can provide images of heart structures, it cannot detect blood flow.

I’ll not rant too much on the technique (least I end up reposting the entire article) but please do read it here if you are interested.

I personally feel that such a technique will benefit cardiac patients tremendously as they do not have to undergo several different procedures (the trauma, cost and time).

I reckon that if such a technique is adopted and set as a standard, then cardiology imaging might chage somewhat (imagine the impact to cardiovascular PACS… interesting isn’t it)
