Expect the exam to last no more than an hour, depending on the preparation needed and whether it includes the use of contrast medium. The scan itself may take just a few minutes.
- During the CT scan you lie on a narrow table that slides through the opening of a large device called the gantry. The table can be raised, lowered or tilted. Straps and pillows may help you stay in position. During a CT scan of the head, the table may be fitted with a special cradle that holds your head still.
- As the X-ray tube rotates around your body, the table slowly moves through the gantry. While the table is moving you may need to hold your breath to avoid blurring the images. You may hear clicking and whirring noises. Each rotation yields several images of thin slices of your body
The patient is placed on a sliding table and positioned comfortably. Then the radiologist and technologist leave the room and the individual MRI sequences are performed. The patient is able to communicate with the radiologist or technologist at any time using an intercom. Also we allow a friend or, if a child is being examined, a parent to stay in the room.
Ultrasound waves cannot penetrate air & bone and hence sonography has limited applications in regions like the skull and chest
No harmful effects of sonography are known even on the embryo of the foetus of a pregnant women.
Colour Doppler is colour-encoded sonography of the blood vessels. Blood flow is seen in colour. It is like sonography and there is no involvement of any injection of contrast.
3D sonography is 3 Dimensional display of the surface of a structure like a foetal face/spine or any other part of the body.
