X-rays are a form of energy- like light and radio-waves. Unlike light waves X-rays have enough energy to pass through human body. As the radiation moves through the body, it passes through the bones and tissues differently. This allows the radiologist to create images of them. X-ray exams provide valuable information about a patient’s health and help the doctor make an accurate diagnosis.

The amount of time depends on the imaging exam performed. Most general x-ray exams take no more than 15 minutes. The contrast related procedures take approximately 30 minutes, unless told otherwise.

The amount of radiation from one adult chest X-ray (0.1 mSv) is about the same as 10 days of natural radiation from the environment (background radiation).

Depending on the type of diagnostic imaging procedure, these exams like ultrasound and MRI are generally safe for pregnant women.

According to the American College of Radiology, no single diagnostic X-ray results in radiation exposure enough to threaten the health of the developing embryo or fetus. However, in Bharati Hospital X-rays of pregnant women are taken only if specifically asked for by the treating doctor and with full shielding of the abdomen.

For upper abdomen ultrasound Patient requires to reach the department after six hours of fasting (water is allowed).

For ultrasound of the kidneys and pelvis the patient is required to come with a full bladder.

For a non-contrast CT scan no preparation is required. However, if CT scan is done with contrast the patient should come to the department after a 4 to 6 hours fast and with latest blood urea / Serum creatinine report.

Patient should discuss with the treating physician regarding any implant anywhere in the body (knee / hip implants, pacemakers, cochlear implants etc.). This information should be conveyed to the Radiologist.

For a non-contrast MR scan no preparation is required. However, if MR scan is done with contrast the patient should come to the department with latest blood urea / Serum creatinine report.

The best way to prepare for diagnostic imaging if you are claustrophobic is to first educate yourself about what to expect. Some procedures, like CT scans, aren’t completely enclosed, so patients do not face any problem.

However, some patients may develop anxiety within the MR machine. If the patient is still worried about being claustrophobic during the procedure, meditation, deep breathing or listening to music may work. Ask the Radiologist as many questions as you need to feel comfortable. If necessary mild sedation can be administered.
