Practice Recommendation for Measuring Washout Rates in I-BMIPP Fatty Acid Images.

The purpose of this practice recommendation is to specifically identify the critical steps involved in performing and interpreting I-β-methyl-iodophenyl-pentadecanoic acid (BMIPP) single-photon emission computed tomography (SPECT) and measurement of washout rate (WR) from the heart. This document will cover backgrounds, patient preparation, testing procedure, visual image interpretation, quantitation methods using planar and SPECT studies, and reporting of WR. The pitfall and some tips for the calculation of I-BMIPP WR are also included.

A novel risk score on admission for predicting death or need for surgery in patients with acute type A intramural hematoma receiving medical therapy.

There has been continuing discussion regarding the treatment strategy for acute type A intramural hematoma (IMH). Most patients are treated conservatively in Japan; hence, predicting fatal events and stratifying risks based on results normally obtained on hospital arrival are important. We aimed to examine the incidences and risk factors of death or need for surgery for acute type A IMH in patients receiving medical treatment and to identify high-risk patients using clinical findings on hospital arrival.

[Usefulness of technetium-99m tetrofosmin single-photon emission computed tomography for short-term risk stratification in patients with acute chest pain in the emergency room].

Objectives: High-risk patients with acute coronary syndrome are difficult to distinguish from low-risk patients with chest pain in the emergency room. Technetium-99m (99mTc) tetrofosmin single-photon emission computed tomography (SPECT) was investigated to exclude high-risk patients with chest pain in the emergency room.

Methods: 99mTc-tetrofosmin SPECT was evaluated using a four-point scoring system in 228 patients (144 men, 84 women, mean age 68 +/- 12 years) with chest pain.
