What is a myelolipoma?
100
This is the ORADS assignment for this lesion:
What is O RADS 2?
Hemorrhagic cyst.
200
This modality is more sensitive in detecting smaller adrenal adenomas.
What is CT?
Better spatial resolution, smaller slice thickness, less respiratory artifact.
300
This Hounsfield density or more of a renal lesion on a noncontrast CT scan denotes a Bosniak II lesion.
What is 70 Hounsfield units?
300
Ancillary features such as restricted diffusion or T2 hyperintensity can upgrade a lesion to any LIRAD category except this one.
What is LIRADS 5?
400
This follow up exam is preferred in working up an adrenal lesion between 10-30 HU on a noncontrast CT scan.
What is MRI?
More sensitive in detecting intracytoplasmic lipid.
If > 30 HU, CT washout protocol is better.
400
This sequence can raise a PIRADS 3 lesion to a PIRADS 4 lesion in the peripheral zone.
What is DCE? Dynamic contrast enhanced sequence.
PZ: DWI is dominant factor
TZ: T2 dominant, DWI 4/5 raise 2 to 3. DWI 5 raise 3 to 4.

This patient has which DSM-5 diagnosis?
What is bipolar disorder?
