Abstract
OBJECTIVE:
To determine the frequency and risk factors for long-term myocardial perfusion scintigraphy abnormalities in patients with Kawasaki disease (KD).
METHODS:
A cohort of patients with KD at least 3 years after disease onset and with persistent coronary artery aneurysms (CAA) (group 1) or without CAA (group 2) underwent stress-rest myocardial single-photon emission computed tomography (SPECT). Clinical and laboratory parameters at disease onset were considered to assess their predictive value for the development of myocardial perfusion abnormalities.
RESULTS:
Forty patients, 20 in group 1 and 20 in group 2, entered the study. The two groups turned out to be comparable for demographic, clinical and laboratory characteristics. Five patients (12.5%), two in group 1 and three in group 2, had abnormal myocardial perfusion assessed by SPECT. Neither the presence of CAA nor the overall cardiac involvement at the disease onset significantly increased the risk for these abnormalities.
CONCLUSION:
Cardiac SPECT abnormalities are not unusual in KD and can be found in patients with or without CAA. If confirmed in a larger cohort of patients, these preliminary data indicate that careful long-term cardiac follow-up should be considered, regardless of the presence of CAA.

Mo-99/Tc-99m Generator Shortage: Free, Web-Based Software
No full textThe article describes a free, Web-based software for calculating the theoretical/estimated 99Mo/99mTc generator yield precisely, taking elution efficiency into account. Such a system should enable the yield of multiple elutions of the generator on the same day as the first elution to be calculated, using the Apache Web server (www.apache.org) and PHP (www.php.net). After inputting
the link (www.rad.unipd.it/nucmed/decay/), the user is prompted to complete a form that is currently provided in American/English and Italian.
The system is simple to use and requires only 5–6 values, which are: generator calibration date; generator arrival date; 99Mo (in GBq) calibration activity declared by manufacturer; number of hours after first elution when second elution is to be performed (and, if a third elution is needed, the number of hours after the second elution when the third elution is to be performed); and elution efficiency (0.9 is the predefined value)
