![Page 2: Aarthi scan's](https://reader037.fdocuments.in/reader037/viewer/2022102323/5467b20baf795936798b72fa/html5/thumbnails/2.jpg)
Diagnostic Imaging is revolutionized by the arrival of computers and software.
Newer technology is still developing due the advancements in software in medical imaging.

What is Multislice CT?
Also known as – MDCT…
![Page 7: Aarthi scan's](https://reader037.fdocuments.in/reader037/viewer/2022102323/5467b20baf795936798b72fa/html5/thumbnails/7.jpg)
ADVANTAGES Reduced scan time( single
breathhold imaging possible).
Excellent resolution
Isotropic resolution in any direction

Cardiac Imaging
![Page 10: Aarthi scan's](https://reader037.fdocuments.in/reader037/viewer/2022102323/5467b20baf795936798b72fa/html5/thumbnails/10.jpg)

What does Cardiac CT do ?
Calcium scoring Viewing the four major vessels Vessel analysis Stenosis Quantification Plaque differentiation Stent imaging Function Assessment
![Page 12: Aarthi scan's](https://reader037.fdocuments.in/reader037/viewer/2022102323/5467b20baf795936798b72fa/html5/thumbnails/12.jpg)
Who Should get Cardiac CT Done ?
Patient is Asymptomatic : Family history of coronary artery disease Persistent high triglyceride levels and other high risk factors
such as smoking, diabetes, etc. ECG abnormalities on a routine health check-up Equivocal (plus/minus) abnormalities on a routine stress test, insurance or as part of a routine health check-up Moderate to severe hypertension Prior to non-coronary surgery in the adult population, etc Pre-ASD repair
Pre-valvular repair Pre-tumor surgery
![Page 13: Aarthi scan's](https://reader037.fdocuments.in/reader037/viewer/2022102323/5467b20baf795936798b72fa/html5/thumbnails/13.jpg)
Who Should get Cardiac CT Done ?
The Patient is Symptomatic :
Atypical chest pain (right side, shoulder tip, etc.)
?Coronary ?Aorta ? Pulmonary.
Anomalous coronary arteries, ectasia or aneurysms
![Page 14: Aarthi scan's](https://reader037.fdocuments.in/reader037/viewer/2022102323/5467b20baf795936798b72fa/html5/thumbnails/14.jpg)
Other Indications:
Post-bypass
Post-stent
For stents larger than 3mm in size, cardiac CT is an excellent tool for assessing in-stent lumen. For stents smaller than 2.5mm, the results are still equivocal.
Tumors Cardiac CT is a good tool for assessing cardiac neoplasms
![Page 15: Aarthi scan's](https://reader037.fdocuments.in/reader037/viewer/2022102323/5467b20baf795936798b72fa/html5/thumbnails/15.jpg)

Calcium score
Plaque burden Probability of significant CAD
0 No identifiable plaque Very low, generally<5%
1-10 Minimal identifiable plaque Very unlikely <10%
11-100 Definite,mild atherosclerotic plaque burden
Mild to minimal coronary stenoses likely
101-400 Definite, moderate atherosclerotic burden
Non-obstructiveCAD highly possible, although obstructive disease possible
>400 Extensive atherosclerotic burden
High likelihood (>90%) of atleast one significant coronary stenosis

Advantages of 64-slice CT angiography as compared to invasive angiography
Better depiction of coronary anomalies
• Non-invasive
• More cost-effective
• Clear visualization of calcium deposits and plaque morphology
• Better delineation of stenoses at the origin of the right and left coronary artery
• True 3D imaging
• “One-stop shop” analysis—coronary arteries, valves, ventricular analysis, myocardial mass, plaque morphology, lung parenchyma

Disadvantages of MDCT ( very few).
No direct assessment of flow through the vesselsMassive calcifications and stents cause beam hardening artifacts, causing false-positives
Need for β-blocking medication when heart rates are elevatedNo interventions are possible during the examination
