| Radiology
has become increasingly interventional, therapeutic
as well as diagnostic & good coverage of these procedures
is presented by internationally acknowledged practicing
experts.
The department of Radiodiagnosis & Imaging is equipped
with advanced state of the art 16 slice Somatom Sensation
Cardiac CT scanner with optimized performance for cardiac
& cardiovascular applications. The real value of
this CT scan is its ability to provide a non –
invasive means of examining internal body structures
including heart & diagnosing disease. Our new multislice
CT scanner allows very fast scanning ------- so fast,
in fact that most scans can be performed in less than
a minute. These subsecond scans can even capture images
of the heart between beats & result in much improved
image quality because of decreased patient motion. Our
new scanner offers virtually unlimited isotropic volume
acquisition with 16 simultaneously acquired slices &
supports 0.37 sec/3600 rotation time for cardiac applications.
With ECG gating and faster scanning CT coronary angiography
is possible & because of its non-invasiveness, OPD
basis & low cost of the procedure it is considered
as ‘gate-keeper’ for the catheter coronary
angiography. Full converge of coronary tree is acquired
in a single breath hold. The major advantage over conventional
angiography is the ability of visualize the coronary
wall as well as the coronary lumen. Calcified &
non-calcified atherosclerotic lesions can be visualized
in the coronary wall. Coronary Calcium Scoring is an
effective screening tool for detection of the earliest
appearance of coronary artery disease & can be used
as marker for progression of coronary atherosclerosis.
In addition to cardiac imaging, other applications
of 16 slice CT include – motion free imaging of
major mediastinal vessels, isotropic volume imaging
of the thoracic & abdominal vasculature, submillimeter
resolution studies of the carotid, cerebral & renal
vessels in pure arterial phase, long range peripheral
angiography, whole body angiography in many patients
to diagnose or to exclude suspected vascular lesions
( e.g – aneurysm, dissection, thromboembolism
etc.) with Real time MPR, 3-D reconstruction.
Body CT has supplanted or encroached upon other radiological
procedures. Rapid, multiphasic contrast enhanced imaging
for various organs systems such as Neuro, Chest, hepatobiliary,
pancreatic, Gastrointestinal is also possible with virtual
endoscopy, CT tracheobronchography, CT cholangiography
& colonography.
CT bronchoscopy and colonoscopy allow us to have an
endoscopic view distal to a lumen – obstructing
lesion that cannot be bypassed by a conventional scope.
Other major advantages of MSCT are higher patient comfort
– in the form of shorter and fewer breath holds
in body imaging, avoiding awkward positioning for coronal
imaging, minimizing sedation for pediatric patients.
Critically ill patients can also be scanned much faster.
1.5 tesla Cardiovascular MR is another newer modality
installed in the department for the non-invasive imaging
of heart & great vessels. MR angiography is a non
invasive method to evaluate the patency of blood vessels
without resorting to invasive conventional X-ray angiography.
MR digital substraction angiography ( MRDSA) is performed
with intravenous injection of MR contrast in an arm
vein. It can be performed in the neck (carotids), head,
body, arm & body. In addition whole body MR imaging
can also be performed with this scanner in a very short
time.
General ultrasound is designed to keep pace with newer,
advances & to cover all areas of ultrasound. The
areas include abdominal ( liver, biliary, pancreas,
gastrointestinal tract, peritoneal and abdominal wall),
retroperitoneum ( vascular, general, retroperitoneal,
kidney & lower urinary tract), pelvis, musculoskeletal,
breast, chest, neck, small parts & interventional
chest & abdominal ultrasound. Color Doppler ultrasound
scanner with convex, linear, sector, transcranial, pediatric
& endocavitory, transducers is used to perform ultrasound.
For the conventional radiography & diagnostic procedures
department has 800 MA set with image intersifier and
seven portable X-ray machines.
To expedite developing & processing of the films,
four automatic processors have been installed.
