Objective 1
A patient suspected of having the right lung is produced radiographic picture of the
chest diseases.
Question: On what is the principle of obtaining images on X-ray film?
Answer: On the particular tissue differently to detain x-rays.
Objective 2
The patient, long-suffering from cardiovascular disease, there is a pacemaker. On
radiographs of OGC in the right lung is determined abnormal shadow with irregular contours. To
clarify the diagnosis the doctor recommended to do a CT or MRI. Which diagnostic method can be
used in this particular case?
Answer: MRI.
Objective 3
Patient pain on an empty stomach in the stomach. The doctor recommended to confirm the
diagnosis X-rays and produce esophagogastroscopy stomach. With the passage through the small
intestine. What a contrast agent should be used for X-ray of the stomach?
Answer: Barium sulphate.
