Dear Doctor,
SKS Hospital
is proud to be the first hospital in this region and the fourth
in South India to install a 128-slice
CT scanner.
The new scanner, Somatom Definition
AS+ from Siemens, with its 128
slices per rotation and fast rotation speed of 300 milliseconds,
is the fastest in the industry on this platform, enabling
acquisition of 426 crystal clear images per second with visualization
of the finest anatomical details. This rapid image acquisition
coupled with a very high spatial resolution (0.3mm isotropic
resolution) allows us to reliably visualise the coronary arteries
and the beating heart with high resolution. The scanners high
resolution and in-built validated measurement software permit
highly accurate assessment of Coronary Arterial Stenosis and
the visualisation of stents for evaluation of patency. The
new and unique Adaptive Step and Shoot technique facilitates
a Coronary CT Angiography (CTA) to be performed with a low
radiation dose (about 1 to 3mSv).
Multislice CT Angiography (MDCTA) is currently the best non-invasive
test that is available to exclude Coronary Artery Disease
in the low to intermediate risk patient with a Negative Predictive
Value greater than 99%. It can visualise early atherosclerotic
disease in the form of soft (fatty or fibrofatty) plaques
and non-obstructive wall calcification before they are detectable
on conventional invasive catheter angiography. It can be used
to clear patients for therapeutic catheterization or surgery.
Coronary MDCTA can be used to evaluate the status of stents
or bypass grafts (post-CABG). Coronary MDCTA detects anomalies
in the coronary arterial anatomy, including myocardial bridging.
MDCT can also evaluate cardiac wall motion and valve function
this information comes with extra reconstructions and post
processing. Echocardiography and Cardiac MRI take more imaging
time but offer superior capability without radiation.
Triple Rule Out study for acute chest pain is a promising
MDCT technique that allows clinicians to rule out Coronary
Artery Disease, Aortic Dissection and Pulmonary Embolism in
a single scan that is done in a few seconds.
MDCT is also extremely useful in the evaluation of cardiac
and pericardial structural abnormalities including masses,
thrombus, etc.
In addition to Coronary CTA, the scanner has the speed and
range to perform Whole Body Angiography (from Carotid arteries
to the Dorsalis Pedis artery).
With its high speed, adaptability and image quality, all other
routine CT scans are performed much faster and more accurately.
The scanner is equipped with many advanced applications including:
· Extremely detailed, colourful and realistic 3D Volume
Reconstructions.
· Virtual Endoscopy for the Colon and Tracheobronchial
tree.
· Whole Brain Perfusion that assesses blood flow to
the entire brain and helps with the early diagnosis of
Ischemic stroke. Definition AS+ is the only scanner in the
market that performs Whole Brain Perfusion.
· Neuro DSA, which gives a complete Carotid & Cerebral
CTA with the click of a button after a routine plain &
contrast-enhanced scan of the head & neck region.
We invite you to utilize the advanced capabilities of this
new scanner for your patients' needs. |
