N/A Objective : The TDX analyzer, an automated fluorescence polarimeter, has been utilized to assess surfactant content in amniotic fluid. Amniostat-FLM is an immunologic semiquantitative agglutination test for determining the presence of phosphatidylglycerol in human amniotic fluid at concentration indicative of fetal lung maturity. We evaluated the usefulness of the recently introduced TDx-FLM assay in determining fetal lung maturity. Methods : Seventy-three samples of amniotic fluid were analyzed. Among them, 18 samples were compared with Amniostat-FLM assay. Results : Surfactant/albumin ratio using TDx-FLM assay increased with longer gestational age. And the concordance rate between Amniostat-FLM assay and TDx-FLM assay was 66.9%. Conclusion : The TDx-FLM assay appears to be a useful test in the field of fetal lung maturity testing.

Systemic lupus erythematosus (SLE) is a multisystemic inflammatory autoimmune disease caused by various autoantibodies and immune complexes. Splenic involvement in SLE includes hypersplenism, splenic atrophy, and splenic infarction, which has rarely been reported. We report a case of SLE with isolated splenic infarction. A 20-year-old female patient was admitted complaining of general weakness, malar rash, and easy fatigue. She was diagnosed as having SLE with thrombocytopenia and received steroid treatment. On the 7th hospital day, she complained of severe left upper abdominal pain with sudden-onset. While abdominal ultrasonography showed only mild splenomegaly, abdominal CT and 99mTc-RBC splenic scintigraphy revealed segmental splenic infarction. She had no evidence of additional thrombotic event or hemorrhage. After administration of high dose steroid, abdominal pain subsided and splenic infarction was resolved.

N/A Purpose: The aim of this study is to better understand the pattern and nature of reverse redistribution (RR) in myocardial perfusion imaging. Materials and Methods: In consecutive 20 acute myocardial infarction (MI) patients, frequency of RR was correlated with that of subendocardial MI that was detected by myocardial contrast echocardiography (MCE). RR was judged to be present when there was more than one grade of worsening in perfusion at 24 hr delayed images compared with the initial rest images. MCE evaluated the significant lack of opacification in the subendocardial myocardium relative to the subepi-cardial myocardium to suggest the subendocardial MI. Kendall's nonparametric correlation coefficiency was calculated. Results: Concordant cases were 15 of 20 (75%) and correlation was statistically significant (p=0.0285). Conclusion: Our results suggested that RR was correlated with MCE-detected nontransmural MI. (Korean J Nucl Med 2000;34:228-33)

Wegener`s granulomatosis (WG) is a syndrome characterized by necrotizing granulomatosis lesions in the upper and lower respiratory tracts, glomerulonephritis, and generalized vasculitis involving both arteries and veins. This syndrome usually affects the upper and lower respiratory tract and the kidneys. Some patients with WG have cardiac involvement such as pericarditis, myocarditis, valvulitis, arrhthymia, coronary arteritis, and rarely cardiomyopathy. Ocular manifestations include keratitis, conjuntivitis, scleritis, retro-orbital granuloma with proptosis. Uncommonly, blindness may occur due to retinal vasculitis and optic neuritis. We report a 45-year-old female patient with WG who had sinusitis and lung nodules. She complained of sudden chest pain. Electocardiography and nuclear myocardial perfusion study suggested transient myocardial ischemia. During the active course of the disease, she complained of severe pain in the right eye-ball with decreased visual acuity. Subsequently, she developed monocular blindness probably due to retinal vasculitis.

A 44-year-old man with a past medical history of splenectomy came to hospital because of epigastric pain. Abdominopelvic computed tomography(CT) showed a soft tissue mass and multifocal variable-sized nodules as well as findings suggestive of cholecystitis. Subsequently, he underwent Tc-99m-labeled heat-denatured red blood cell(RBC) scintigraphy to evaluate the mass and nodules. The scintigraphy confirmed multifocal peritoneal splenosis in the abdominopelvic cavity. (Nucl Med Mol Imaging 2006;40(3):190-191)
종격동 종괴를 수반한 결핵성 심낭염 1 예의 Ga-67 SPECT 소견

We present a case of a 31 year-old male patient with tuberculous pericarditis with mediastinal mass that showed increased uptake on Gallium-67 image. Gallium-67 scan was performed to evaluate the activity of the superior mediastinal mass, which was detected on chest CT. A rim of intense activity around the heart was observed, but increased uptake was not seen in the mediastinum. However, on maximal contrast-enhanced SPECT images, a small focus of faint uptake was observed in the superior mediastinum. This finding implied that there was an active tuberculosis in the pericardium and inflammation in the superior mediastinal mass. This case demonstrated that Gallium-67 scinitigraphy was helpful for the diagnosis of tuberculous pericarditis. (Korean J Nucl Med 200135:280-285)
