A CT scan is a non-invasive diagnostic procedure that uses an advanced scanner to produce detailed body images in crosssections. It can help diagnose a wide array of medical conditions affecting the muscles, fat, organs and blood vessels. It provides better visualisation of the body’s inner organs than regular X-rays.
You will be asked to lie down on an examination table next to the USG machine. A diagnostic medical sonographer applies a jelly-like substance (ultrasound gel) to the body part that must be examined. A hand-held device called a probe attached to the machine is slowly applied over the gel and moved back and forth over the skin to visualise the organs and tissues underneath. The probe releases sound waves, which echo as they hit a dense object, like an organ or bone. The sound waves are ultrasonic, which means their frequency is too high for the human ear to hear. The echoes are sent back to a computer, which forms a picture on the machine’s screen. These are interpreted by the radiologist or sonologist, at Karauli Diagnostics, providing the best ultrasound in Varanasi.
To visualise internal organs better, special probes are inserted into body cavities. For example, in a Transesophageal echocardiogram, the probe into the oesophagus to see the heart better. In a Transrectal ultrasound, the probe is inserted into the rectum to view the prostate and a Transvaginal ultrasound uses a probe in the vagina to view the uterus and ovaries.
A USG is used as imaging guidance for needle biopsies or fluid tapping in some cases. In a USG guided procedure, the probe is used to visualise the area that is being examined. A needle is inserted into the soft tissue or organ to remove a sample of tissue or fluid from the site, which can then be tested in the laboratory to find out the cause behind the medical condition. It is commonly used for: ● Ascitic tapping: removal of fluid from the abdomen ● Pleural fluid tapping: removal of fluid from the outer lining of the lungs
Physicians may ask you to get an ultrasound to diagnose various conditions affecting your internal organs. For example, in the
Spleen: for splenomegaly
Thyroid: for thyroid nodules or goitre
Testicles: for hydrocele and testicular cancer
Uterus: for fibroids, endometrial thickening, follicular staging, confirmation of pregnancy and checking the baby’s growth and development at various trimesters.

Doctors recommend ultrasound tests for various purposes such as:
Yes, you can drink water before an ultrasound test. Some ultrasound test requires a full bladder to visualize the internal structure properly.
Yes, liver ultrasound which is a type of transabdominal ultrasound can detect various types of liver diseases such as hepatitis, fatty liver, cirrhosis of the liver, liver cancer as well as gallbladder stones.
There are various diseases can be detected by Ultrasound such as:
The level 2 ultrasound is like standard ultrasound that is performed during the second trimester to monitor the development of the foetus. This test evaluates the structure of organs, umbilical cord, heart rate, size as well as the level of amniotic fluid to detect birth defects.
Depending on the type of ultrasound test, the Ultrasound scan takes 15 minutes to 30 minutes to complete.
