Mallya Hospital 24/7 services of Radio-diagnosis & Imaging department provide non-invasive and interventional radiology services. Operational round the clock, it not only serves the diagnostic needs of all other departments in the hospital but caters to the diagnostic requirements of most of the neighboring Hospitals and Nursing Homes. It deals with Radio diagnosis and imaging and is carried out using following state ľof-the-art equipment.
1. MRI Scanner 1.5 Tesla
2. CT Scanner: 64 Slice Scanner for whole body and cardiac evaluation
It is a whole body CT scanner with high end features useful for non invasive Coronary angiography, Renal angiography, Cerebral Angiography etc. This advanced equipment could provide 64 slice images in a single breath hold. The whole process of scanning the body region takes less than 1 minute.
Cardio CT Angio is a procedure performed using a multi-slice CT. The current multi-slice CT at Mallya Hospital that exquisitely produces coronary artery images is a 64 -sslice CT scanner from Philips.
This scanner has a special X-Ray tube and rotation speed, capable of performing 3 rotations in a second. In each rotation, 64-slices are produced, giving us approximately 194 slices per second. This is fastest scanner in the industry currently. Speed is extremely important in our ability to "Freeze" the heart. Since the heart is a rapidly moving structure, the only way to image structures within it, is if we can scan as fast as the heard beats or close enough.
All scans are gated to the ECG trace. This allows us to position our data acquisition accurately in specific phases. Using this modality we can perform the following procedures as part of a cardiac CT examination.
ACR Statement on Noninvasive Cardiac Imaging includes the following applications using Cardiac CT.
The following are situation in which a cardiac CT is of use: "To Rule Out Coronary Artery Disease". The ability of cardiac CT to rule out coronary artery disease exceeds a predictive value of 99%. This means that when the study is reported to be normal, it will be normal.
This makes it a more accurate test than stress-testing, stress-echocardiography, stress-thallium and stress-perfusion MRI. More importantly, the heart does not have to be stressed to get this information. "To Rule Out Coronary Artery Disease" is an issue that often arises in the following situations:
The patient is Asymptomatic: (i.e., there are no problems, such as chest pain or breathlessness, but coronary artery disease needs to be ruled out)
1. Family history of coronary artery disease.
2. Persistent high triglyceride levels and other high risk factors such as smoking diabetes etc.,
3. ECG abnormalities on a routine health check up.
4. Equivocal (plus/minus) abnormalities on a routine stress test, done prior to employment, insurance or as part of a routine health check up.
5. Moderate to severe hypertension
6. Prior to non-coronary surgery in the adult population etc,
The patient is Symptomatic (i.e., there is chest pain or breathlessness, but the physician/ cardiologist is not convinced that there is coronary artery disease)
You will be asked to change into a hospital gown. A skilled healthcare provider will start an IV in your arm, as well as attach cardiac monitoring leads to your chest. You may be given mediation either orally or intravenously to help lower your heart rate for this examination
You will lie on a scan table that slides slowly into a large circular opening in the scanning machine that looks like the hole in a doughnut. The CT staff will be in the control area, adjacent to the CT room. You will be in sight of staff through a window. Speakers inside the scanner will allow staff to talk with you and hear you. The technologist will be watching you at all times and be in constant communication.
The CT staff will take preliminary scans to help define the area to be imaged. During this time you will be asked to hold your breath. Once the plan has been established, you will receive an injection of contrast media through the IV to highlight the coronary arteries. As the contrast is injected, it may feel warm or give your mouth and metallic taste. This is a normal occurrence and will pass quickly. It is important that you remain very still during the procedure.
You may resume your normal diet and activities immediately following your procedure. Do drink extra water to help flush the IV contrast from your system. This generally takes 24 hours.
3. Ultrasound and Color Doppler. Ultrasound is a non invasive highly accurate technique to evaluate the abdomen and small parts. Ultrasound is extremely useful in Obstetrics and Gynaecology.
Ultrasound can also be used for guiding interventional procedures like biopsies and abscess drainage.
Color Doppler is a good non invasive test to evaluate the carotid arteries and peripheral and abdomen vessels.
5. CR -> Computerized Radiography.
This novel technology has brought in revolution in the very basics of X-Ray imaging. CR films are easy to handle and is instantly developed. The conventional system of film developing etc., is not involved.
The prevalence of under developed or less clarity images is nil in CR system and patients stand beneficial due to nil chance of repetition of the procedures.
The images are could also be loaded in a CD and being soft copy dealing with the images also handy.
