What imaging drawback is associated with the MOTSA technique?

The MOTSA (Multiple Overlapping Thin Slice Acquisition) technique is utilized in MRI to improve the quality and detail of scanned images. However, one of the notable drawbacks of this method is the longer imaging times associated with the need to acquire multiple overlapping slices. The necessity for multiple acquisitions means that the scanner works for an extended period, which can lead to increased overall scanning time for the patient.

This extended duration can also cause discomfort for patients who may need to remain still for longer periods, and it increases the demand on MRI resources, potentially limiting the number of patients a facility can accommodate in a given timeframe. While the benefits of enhanced detail and resolution are significant, the trade-off of time efficiency is a critical consideration in clinical practice.

Understanding the implications of longer imaging times is important for practitioners, as it affects scheduling, patient throughput, and overall workflow in MRI departments.
