The following kVp setting produce greatest contrast in radiograph image
1. 70 kVp
2. 80 kVp
3. 90 kVp
4. 100 kVp
Radiology
Answer: 1
The kVp setting that produces the greatest contrast in a radiograph image is 70 kVp.
Lateral cephalogram is used for all of the following except
1. To assess where excessive growth is occuring
2. To compare the growth patterns with previous radiograph
3. To assess level of posterior alveolar bone
4. To assess soft tissue profile
Radiology
Answer: 3
A lateral cephalogram is used to assess the level of posterior alveolar bone.
The radiograph showing one of the best view of a fracture of
1. The orbital rim is the 30 degree occipitomental view
2. The orbital floor is the 10 degree occipitomental view
3. The orbital medial wall is the lateral skull view
4. The orbital roof is the lateral skull view
The radiograph showing the best view of a fracture of the orbital floor is the 10-degree occipitomental view.
Internal derangement of the TMJ can be best diagnosed by
1. MRI
2. CT scan
3. Arthrography
4. Panoramic view
Radiology
Answer: 1
Internal derangement of the TMJ can be best diagnosed by MRI.
Brown discolouration seen in old radiographic films is due to
1. Overdevelopment
2. Underdevelopment
3. Incomplete fixation
4. Exposure to light
Radiology
Answer: 3
Brown discoloration seen in old radiographic films is due to incomplete fixation.
Which of the following provides superior definition of soft tissues, bony details and physiologic information about the TMJ joint
1. MRI
2. Pantomograph
3. Arthrography
4. CT scan
Radiology
Answer: 3
The imaging technique that provides superior definition of soft tissues, bony details, and physiologic information about the TMJ joint is arthrography.
The ingredient of the fixing solution of the X-ray is
1) Hydroquinone
2) Elon
3) Sodium bisulphate
4) Acetic acid
Radiology
Answer: 4
Acetic acid is a key ingredient in the fixing solution used in radiography. It acts as a stop bath, neutralizing the developer and maintaining the acidic environment necessary for proper fixation. Hydroquinone and elon are developer agents, while sodium bisulfate is not typically part of the fixing process.
Imaging technique with MAX radiation exposure to patient?
1. chest x-ray
2. MRI
3. CT scan
4. bone scan
Radiology
Answer: 3
Explanation: Among the imaging techniques listed, a CT (computed tomography) scan typically involves the highest radiation exposure to the patient. This is due to the multiple X-ray images taken from different angles to create cross-sectional images of the body.
