Normally, we do not give appointments for routine ultrasound examinations and other investigations. However, peripheral Doppler examinations are done with appointment only.

Appointment is also required for ultrasound or CT guided FNAC, Echocardiography, TMT, Executive Health check etc.


Upper abdomen and whole abdomen examinations

It is essential to come with overnight fasting for these examinations. Investigations will take 2-3 hrs or even more to complete as oral contrast is generally given and it takes time to reach colon. We normally do not ask patient to come with full bladder as it will generally fill during the course of administration of oral contrast. However, you are required not to pass urine during this examination.

 KUB and lower abdomen examinations

There is no need of fasting for these examinations but full bladder is a requirement. Further, avoid examination immediately after taking food. A gap of 2 hrs is advisable whenever contrast is to be administered.

Head examination

Normally no preparation is required for these examinations. But in case of children and those with neurological problems, may need to be sedated/anaesthetized as good examination can not be done, if patient is moving his/her head.

Allergy to drugs and contrast media

Though we use non-ionic contrast media which has very few reactions, however, a severe reaction is a possibility. If you are allergic to any drug or contrast media, you must tell us. This may require modification and different planning for examination.


Generally no preparation is required for routine x-ray examinations. But x-ray of abdomen/ KUB/ LS spine will require you to have preparation previous night with charcol/unienzyme and some laxatives.

Special x-ray investigations will required additional preparations and these will be given to you at the time of appointment itself.


When to come empty stomach?

All ultrasound examinations of upper abdomen or whole abdomen require you to come empty stomach. This is essentially to see gall bladder in distended condition. However, practically, we are able to see it well in most of the patients and as a rule, we do not recommend empty stomach. But once in a while, if gall bladder is completely contracted, we may suggest you to come empty stomach again to have a better look at gall bladder. Coming empty stomach in the morning, however, helps in one more way as there is less gas in abdomen which helps in better visualization.

When to come full bladder?

Generally all lower abdomen and whole abdomen examinations require full bladder. Also examinations of KUB and early pregnancy (generally up to 3-4 months) will require full bladder. Full bladder means you have to take lot of water at least 1-2 hrs before examination and not pass urine. A well distended urinary bladder helps in seeing uterus, ovaries and adnexa properly in females and prostate in males. It also helps in seeing small stones in bladder and ureters in KUB examination. It is important to note that an urge to pass urine does not indicate you are having full bladder. A really full bladder will make you uncomfortable. We need you to have full bladder, but you should be comfortable. For these examinations, come with some margin to wait as your turn may not come immediately on reaching clinic.

Examination of children:

Examination of small children is difficult if they are crying. A well satisfied child is less prone to crying. We do not normally recommend them to be kept empty stomach except in some situations. Sometimes child may need to be sedated.


Have a good meal 30 – 60 minutes prior to appointment. Drink 1 to 2 glasses of fruit juice 20-30 minutes prior to the appointment unless otherwise ordered by your physician. We would like your baby to be awake during your exam for more thrilling experience. We would also like some fluids in your bladder to bring the baby’s head out of the pelvis, but it does not need to be extremely full.


Do not come for these investigations immediately after taking meals.


Do not require any preparations.


 X-ray, CT scan and Mammography are generally not advised during pregnancy. If you are pregnant or suspect, please inform the doctor before these investigations.
