1.Dosimetry and MIRD for Re-188 Liquid Balloons.
Korean Journal of Nuclear Medicine 1999;33(2):222-227
Re-188 is suitable for endovascular liquid-balloon brachytherapy for the prevention of restenosis after angioplasty. Re-188 was concentrated to 3700 MBq/ml and labeled with DTPA. According to dosimetric calculation, it took 420 seconds using Re-188 solution with concentration of 3700 MBq/ml to irradiate 17.6 Gy to the target at 1 mm from the balloon surface. Software was made to estimate the irradiation time. MIRD calculation with dynamic bladder model yielded the whole body dose of Re-188-DTPA as 0.005mGy/MBq in case of balloon rupture and release of the whole amount into the blood.

3.New Imaging Technique in Myocardial Perfusion SPECT.
Korean Journal of Nuclear Medicine 1998;32(1):1-9
Gated myocardial SPECT and attenuation correction gave birth to new insights into the pathophysiology of ischemic myocardial perfusion and function in clinical routine practice. Gated myocardial Tc-99m-compound SPECT improved diagnostic accuracy of coronary artery disease and enabled us to observe motion and thickening of myocardial walls as well as myocardial perfusion at the same time. Quantitative and qualitative assessement of myocardial performance and perfusion let us to understand the myocardial physiology in ischemia and infarction. In every patient who underwent gated perfusion SPECT, we will find ejection fraction, left ventricular volumes and regional wall motion. There are hopes to use gated T1-201 SPECT for the same purpose and to use gated SPECT for evaluation of wall motion and thickening at stress or immediate post-stress. Attenuation correction could improve diagnostic accuracy mainly by increasing normalcy ratio or performance of non-expert physicians. Both gated methods and attenuation correction improved specificity of non-expert physicians in diagnosing patients with moderate pretest likelihood. New imaging techniques will fill the desire of cardiologists examine function and perfusion, and possibly metabolism in their clinical routine practice.
