Advantages and disadvantages of imaging modalities

Approach	Advantages	Disadvantages
X-ray	Cheap and easy to use.	· Not very safe because ionizing radiation can cause cancer or lead to cell mutations. · Does not generate detailed images. · Used to image bones only.
CT	Very detailed and precise.	More ionizing radiation than X-ray.
Ultrasound	Safe, affordable, and simple.	· Low image resolution. · Increase tissue temperature.
MRI	· Can image any body part. · Safe- no ionizing radiation.	· Expensive. · Uncomfortable for patients.
