Table 3. Qualitative Assessment of the Existing MR Sequences for VMs Diagnostic and Interventional Procedures.

	TSE	HASTE	SSFP	T₂W-iSSFP

Image Sharpness	++	–	++	+
Flexibility	+/–	+/–	+	++

We evaluated these sequences in the aspects of image contrast, imaging speed, image sharpness, flexibility, and SAR safety. T₂W-iSSFP shows high performance in all of these aspects, making it a suitable sequence for guiding needle insertion when T₂-weighted real-time imaging is needed. -: bad, +/-: uncertain, +: good, ++: very good.
