The "fixed" SPECT MPI defect: Where are we and where should we be going?
1Cardiac Unit, Massachusetts General Hospital, Harvard Medical School, 14 Fruit Street, Boston, MA, 02114, USA. Gewirtz.Henry@mgh.harvard.edu.
Summary
Myocardial perfusion imaging (MPI) SPECT defects may appear fixed due to technical and physiology factors. Cardiac PET MPI offers absolute myocardial blood flow (MBF) measurements to clarify defect significance.
Area of Science:
- Cardiology
- Nuclear Medicine
- Medical Imaging
Background:
- Myocardial perfusion imaging (MPI) using SPECT can show fixed defects, where imaging results are similar at rest and stress.
- The reasons for these fixed defects are often a combination of technical and physiological factors.

The vacuum level denotes the energy threshold required for an electron to escape from a material surface. It is usually positioned above the conduction band of a semiconductor and acts as a benchmark for comparing electron energies within various materials.
Electron affinity in semiconductors refers to the energy gap between the minimum of its conduction band and the vacuum level and it is a critical parameter in determining how easily a semiconductor can accept additional electrons.

Calculating subtransient fault currents for three-phase faults in an N-bus power system involves using the positive-sequence network. When a three-phase short circuit occurs at a specific bus, the analysis uses the superposition method to evaluate two separate circuits.
In the first circuit, all machine voltage sources are short-circuited, leaving only the prefault voltage source at the fault location. The positive-sequence bus impedance matrix can be determined by solving the nodal equations,...
