SEARCHING FOR THE UPPER LIMITS OF MP-SPECT

The case study shown below is an MP-SPECT study from a 430 pound patient whose body habitus exceeded the rotational limits of the Philips/ADAC Vertex SPECT system. It appeared that the study would have to be canceled which is a circumstance that is repeated in many imaging labs across the country every day.

With no other available option, we were called to inquire about the upper size limits for the MP-SPECT system and accepted the opportunity to investigate this aspect of our system performance. The patient had already received his resting injection (10 mCI of Myoview) so it was logical to use our standard simultaneous dual-isotope MPI protocol and ordered in 4.0 mCi of TL-201.

Pharmacologic stress was performed with Lexiscan. Positioning the patient with his arms at his side took less than 3 minutes and the single acquisition imaging session took 12 minutes. A very grateful patient left the department 35 minutes after the Tl-201 was delivered.

We still don’t know what the absolute limit on patient size is for MP-SPECT but we think the set of normal images shown in the slices below speaks for themselves. Another benefit can be added to the check-list of MP-SPECT advantages.
