All the following are advantages of CT scanning over MRI scanning except
|A||Direct imaging of cortical bone to detect bone trauma, stress frac-tures or tumour invasion|
|B||Open scanner format-little difficulty for claustr-ophobic patients|
|C||Negligible risk of radiation|
|D||CT myelography useful where MRI is contra-indicated|
Negligible risk of radiation
Ionizing radiation is one of the disadvantages of CT. It is also a relative contra- indication in pregnancy.
