As an inexpensive, quick and dynamic imaging technique that also provides high-resolution depiction of the PF and comparison with the contralateral side, ultrasound should be considered the modality of first choice for assessing PF disorders.
MRI is considered the modality of choice for imaging tumours of the oral cavity [ 4] and the pharynx [ 5].
While contrast enhanced magnetic resonance imaging (MRI) is generally considered the modality of choice for staging malignant breast disease and PET/CT is considered the modality of choice for staging distant spread, ultrasound (US) can also be used to assess the local extent of malignant breast disease in many patients.
Multislice CT (MSCT) is often considered the modality of first choice for the distant staging of colorectal cancer (e.g. the detection of metastatic spread to the liver and/or lungs).
