  • It is cost-effective and readily available in most medical facilities

  • The film is sensitive to X-ray radiation and produces high-quality images for diagnostic purposes

Q3. Which of the following image modalities are likely to have less scan

Ans.

Ultrasound and MRI are likely to have less scan radiation compared to CT and X-ray.

  • Ultrasound uses sound waves to create images, no radiation involved

  • MRI uses magnetic fields and radio waves, no radiation involved

  • CT scans and X-rays use ionizing radiation for imaging

Q4. What are the limitations of CT scanning of spine

Ans.

Limitations of CT scanning of the spine include limited soft tissue contrast, radiation exposure, and inability to visualize certain structures.

  • Limited soft tissue contrast can make it difficult to differentiate between certain tissues or pathologies.

  • Radiation exposure is a concern, especially for repeated scans or in sensitive populations.

  • CT scans may not be able to visualize certain structures well, such as nerves or small blood vessels.

  • Motion artifacts can affect image qua...read more

Q5. What is the process of a CT scan

Ans.

A CT scan is a medical imaging procedure that uses X-rays and computer technology to create detailed cross-sectional images of the body.

  • Patient lies on a table that slides into the CT scanner

  • X-ray tube rotates around the patient, emitting X-ray beams

  • Detectors measure the amount of radiation absorbed by the body

  • Computer processes the data to create detailed images

  • Images are reviewed by a radiologist for diagnosis

Q6. How many views for chest xray

Ans.

Typically, two views are taken for a chest x-ray: the posteroanterior (PA) view and the lateral view.

  • The posteroanterior (PA) view is the most common view for a chest x-ray.

  • The lateral view provides a side view of the chest and is often used to assess the position of structures within the chest.

  • Additional views may be taken based on the specific clinical indications or suspected conditions.

  • Examples of additional views include the anteroposterior (AP) view, oblique views, or s...read more
