Two branches of the external iliac artery are the inferior epigastric and deep circumflex iliac
arteries.
Which muscle attaches to the coronoid process of the mandible?
A) Temporalis
Notes:
- The temporalis muscle attaches to the coronoid process, and the masseter attaches to the
rami. The lateral pterygoid inserts into the neck of the mandible, and the medial pterygoid
inserts into the ramus near the angle of the mandible.
The rhomboid fossa of the clavicle is created by the insertion of:
A) Costoclavicular ligament
Normal indentation on the esophagus is made by one of the following:
A) Left atrium
In barium swallow the cervical narrowing of the esophagus is caused
by?
A) Cricoid cartilage
B) Thyroid
A) Cricoid cartilage
From posterior → Cricopharyngeal muscle
Duplex collecting system is most commonly associated with which of the following?
A) Larger than normal kidney
Fanconi anemia
What is the blood supply of the following structure?
A) Recurrent artery of Huebner (Medial lenticulostriate)
B) Lateral lenticulostriate
C) ACA
D) (anterior choroidal was not in the choices)
Depend
Without changing the FOV, how can you improve MRI resolution?
A) Decrease matrix size
B) Increase number of excitations
C) Increase accusation
D) Increase phase encoding
D) Increase phase encoding
Notes:
- ↑ matrix size
- ↑ phase encoding → ↑ scan time → ↑ matrix size → improve resolution.
- ↑ accusation → ↓ resolution.

A) 30 rad
B) 60 rad
C) 300 rad
C) 300 rad
300 rad = 3 Gy
In conventional angiogram if you increase the distance between the patient and the image detector, what will happen?
A) Image magnification
Orthopedic is suspecting a fracture however, it was not obvious in the current image. What method will improve the ability to see the fracture?
A) Kernel algorithm
Notes: Bone Kernel → sharpening the image.
On CT image there are multiple rings in the image. What is the cause of this artefact?
A) Detector drift
The role of the TGC on US is to?
A) Amplification from deep tissues
Notes:
- A way to overcome ultrasound attenuation is time gain compensation (TGC)
Risk of radiation in children in comparison to adults?
A) Higher risk of developing leukemia
What is magnetic susceptibility?

Calculate the effective half-life of I131 which has a physical half-life of 8.04 days and a biological half-life of 25 days:
A) 2
B) 6
C) 12
D) 20
B) 6
Notes:
- Effective half-life = 1/biologic + 1/physical
- Effective half-life is: Smaller than the physical half-life and biological half-life.
What happens to the patient dose if you change the from 30 to 15?
A) Quadruple
In the following patient undergoing CT guided biopsy which is
considered part of safety?
A) Decrease kVp in order to decrease dose
B) Repeat full chest CT scan every time anything is done
C) General anesthesia to decrease breathing artifact
D) Perform CT scan with contrast
A) Decrease kVp in order to decrease dose
Notes:
- ↓ kVp → ↓ radiation
Not same image but similar effect) What changed from image A to B?
A) Increased peripheral sharpness
B) Increased Kvp
A) Increased peripheral sharpness

A) Judet
B) Mortise
C) AP with 15 internal rotations
A) Judet
Raise the affected side by 45° and center to the affected hip.
Judet -> Hip
- AP with 15 internal rotation → knee.
- Mortise → ankle.
Patient presented with incidental adrenal lesion which was inconclusive on non-contrast CT. On post contrast images demonstrated an absolute washout of more than 60 consistent with adrenal adenoma. How many minutes is recommended in this delayed scan?
