Yes, there are other alternatives to a CT scan. CT scans are used for various reasons such as head injury, pneumonia or for confirming a diagnosis of cancer or to screen for cancer. Depending on the reason for testing, alternatives can be used. Some studies suggest using magnetic resonance imaging (MRI) and ultrasound for screening certain cancers. MRIs can also be used in head trauma. Ultrasound can be used in place of CT scans to view the abdomen.

CT scan is considered beneficial mostly when the doctor suspects a disease based on the visible signs and symptoms. CT scan is also recommended when people have a family history or are at a higher risk of certain cancers.

But since CT scan exposes people to a certain amount of radiation, alternatives are usually considered first and CT scans are performed only when they are considered better than other diagnostic tests in a particular patient. 

Cancer is a broad term for more than 200 types of diseases that can be fatal. A CT scan may not show correct results all the time. The same has been confirmed by a hospital website which notes CT scans can show false results, lack of details, miss some tumours and can be inaccurate for monitoring purposes. Hence, a doctor can select a suitable alternative to a CT scan depending upon the suspected location within the body.
