How to search for technician exam questions over the years? I will take the 20 15 medical imaging technician exam soon. I want to do real questions over the years.

Medical imaging technician examination

The time for applying for junior technician in imaging technology major of our college is 1 February 15 to the following year1month, and the examination time is May of the following year. The examination is divided into written examination and man-machine dialogue. I did several sets of questions at home and found that I got a lot of image diagnosis and medical anatomy. I have summarized some key points, which are all common places, and some mistakes are welcome to be pointed out positively. These are just some, I will continue to update and try to pass the exam within one year!

Iodine allergy test methods: sublingual test, intradermal test, venous test, conjunctival test and oral test. Advantages of CT: 1, high density resolution; 2, quantitative analysis can be done; 3. Straight section image; 4. There is no interference from out-of-plane structures.

The use of contrast agent: cholangiography-meglumine diatrizoate; Gastroenterography-medical barium sulfate; Cardiovascular angiography-meglumine diatrizoate, meglumine diatrizoate diiodopeptide, meglumine diatrizoate; Ventriculography-air; Urography-meglumine diatrizoate; Pyelography-sodium diatrizoate; Cerebral angiography-meglumine diatrizoate; Myelography-iodophor and iodobenzene ester; Salpingography-lipiodol CT and spiral CT: the same point: the X-ray tube rotates continuously.

The difference is that the annoying scanning mode of spiral CT data acquisition is that the X-ray tube is changed from reciprocating rotation to unidirectional continuous rotation scanning. The patient (table) moves in one direction at the same time.

The advantages of spiral CT are: first, it improves scanning speed and reduces motion artifacts; Second, because thin-layer scanning can be performed, it can provide better volume data for 3D image reconstruction.

The quality parameter of CT image: 1. Contrast and contrast resolution (density resolution) 2. High contrast resolution and low contrast resolution; Third, spatial resolution; Fourth, noise; Five, uniformity belongs to the projection fiber is the inner capsule and the outer capsule.

Belonging to the ventricular system are: left and right lateral ventricles, the third and fourth ventricles, and the common bleeding site of midbrain aqueduct hypertension: basal ganglia hematoma.

The characteristics of X-rays used in clinic are: penetrability, fluorescence, photosensitivity, ionization perspective and radiography. What are their advantages and disadvantages?

1. Advantages of perspective: 1. The patient can be rotated at will for multi-angle perspective observation; 2. Observe the motor function of motor organs; 3, simple operation and low cost; 4. The inspection results can be obtained immediately; 5. Interventional surgery can be performed under fluoroscopic monitoring.

Disadvantages of fluoroscopy: 1, subtle lesions and thick parts can not be observed clearly; 2, can't leave a permanent record; The patient receives a large dose of radiation.

2. Photographic advantages: 1, clear image and good contrast; 2. Fine lesions and thick parts can be observed clearly; 3. The radiation dose received by patients is small; 4, permanent records, for review and comparison;

Disadvantages of photography: 1, it is not convenient to observe the motor function of motor organs; 2. Complex technology and high cost; It takes a long time to have an effect.

Commonly used special photography includes: tomography and soft X-ray photography. How to protect X-ray inspection?

Staff protection: 1, make full use of all kinds of protective equipment; 2. Control the original discharge line; 3. Reduce scattered lines; 4. Regular health examination;

Subject protection: 1, the distance from the skin to the lesion is not less than 35cm, and the non-projection field is covered with lead skin, especially the gonad and fetus; 2. Reduce the irradiation field.

Selective angiography: percutaneous puncture of artery or vein to place catheter, and under the monitoring of TV screen, the catheter is selectively sent to the target blood vessel. Inject contrast agent for angiography.
