“…MSCT is often the first-line investigation in the study of the oral cavity since it is widely available even in small centres. MSCT has short image acquisition times, good spatial resolution, and provides an excellent assessment of cortical bone involvement [15]. MRI comes at higher operating and technical costs per procedure than MSCT and is still as not widely available as MSCT.…”

The oral cavity constitutes a complex anatomical area that can be affected by many developmental, inflammatory, and tumoural diseases. MultiSlice Computed Tomography (MSCT) and Magnetic Resonance Imaging (MRI) currently represent the essential and complementary imaging techniques for detecting oral cavity abnormalities. Advanced MRI with diffusion-weighted imaging (DWI) and dynamic contrast-enhanced perfusion-weighted imaging (DCE-PWI) has recently increased the ability to characterise oral lesions and distinguish disease recurrences from post therapy changes. The analysis of the oral cavity area via imaging techniques is also complicated both by mutual close appositions of different mucosal surfaces and metal artifacts from dental materials. Nevertheless, an exact identification of oral lesions is made possible thanks to dynamic manoeuvres and specific stratagems applicable on MSCT and MRI acquisitions. This study summarises the currently available imaging techniques for oral diseases, with particular attention to the role of DWI, DCE-PWI, and dynamic manoeuvres. We also propose MSCT and MRI acquisition protocols for an accurate study of the oral cavity area.

“…MRI comes at higher operating and technical costs per procedure than MSCT and is still as not widely available as MSCT. Notably, MRI provides the highest resolution for soft tissues, good accuracy in the detection of bone marrow involvement, and the possibility to identify a perineural tumour spread [15].…”
