Which is better MRI or CT scan for abdomen?
MRI is more accurate than a CT scan or other tests for certain conditions but less accurate for others. The function of the small and large bowel (intestines) is not readily visible. Disadvantages include the high cost, long duration of the scan, and sensitivity to movement.
Is ultrasound or CT scan better for abdominal pain?
CT misses fewer cases than ultrasound, but both ultrasound and CT can reliably detect common diagnoses causing acute abdominal pain.
Is CT scan good for abdomen?

Which is best CT scan or ultrasound?
Comparison chart
| CT Scan | Ultrasound | |
|---|---|---|
| Principle used for imaging | Uses X-rays for imaging | High Frequency sound waves (ultrasound) are used for imaging |
| Details of soft tissues | A major advantage of CT is that it is able to image bone, soft tissue and blood vessels all at the same time. | Detailed with advanced technology |
Which is better CT scan or endoscopy?
Both procedures are relatively safe; CT does expose you to radiation (at a safe level) and if IV contrast dye is used to enhance CT images, some people may be allergic or have the possibility of kidney damage while endoscopy has the risk of bowel perforation and allergic reaction to anesthesia drugs.
