What does MOTSA stand for in MRA?

The acronym MOTSA stands for Multiple Overlapping Thin Slab Acquisition. This technique is utilized in Magnetic Resonance Angiography (MRA) to enhance the visualization of vascular structures. By acquiring multiple overlapping thin slices, this method helps achieve better spatial resolution and contrast, allowing for improved delineation of blood vessels. This capability is particularly crucial in MRA, where precise imaging of the arterial anatomy is necessary for diagnosis and treatment planning. The approach allows radiologists to analyze the acquired slices in a way that minimizes gaps in visualization, ensuring comprehensive coverage of the area of interest, thereby providing clearer and more detailed images of vascular conditions.
