UNLABELLED Electrocardiographically (ECG) gated myocardial SPECT with (99m)Tc-tetrofosmin has been used widely to assess left ventricular (LV) function. However, the accuracy of variables using ECG gated myocardial SPECT with beta-methyl-p-(123)I-iodophenylpentadecanoic acid (BMIPP) has not been well defined. METHODS Thirty-six patients (29 men, 7 women; mean age, 61.6 +/- 15.6 y) with ischem...

UNLABELLED Selective internal radiation therapy (SIRT), a catheter-based liver-directed modality for treating primary and metastatic liver cancer, requires appropriate planning to maximize its therapeutic response and minimize its side effects. (99m)Tc-macroaggregated albumin (MAA) scanning should precede the therapy to detect any extrahepatic shunting to the lung or gastrointestinal tract. Our...

Explaining patterns of asset ownership is a central goal of both organizational economics and industrial organization. We develop a model of asset ownership in trucking, which we test by examining how the adoption of different classes of on-board computers (OBCs) between 1987 and 1997 in uenced whether shippers use their own trucks for hauls or contract with for-hire carriers. We Ž nd that OBC...

Objectives. Determine outcome of the 2005 appropriateness use criteria (AUC) for SPECT in a diverse population of patients and physicians. Background. AUC for SPECT were the first cardiology document to identify 52 clinical indications for imaging, 49 of them for stress SPECT. AUC have been proposed as cornerstone of responsible use of perfusion imaging. Methods. 585 consecutive patients underg...

UNLABELLED BACKGROUND Unspecific pain of the hand/wrist is a diagnostic challenge. Radiographs and planar bone scan are useful diagnostic tools in patients with unspecific wrist pain. Both modalities are deficient, either by not presenting metabolic disorders or due to inadequate anatomical resolution. Single photon emission computed tomography/computed tomography (SPECT/CT) claims to fuse b...

metastatic survey of the patients with known primary malignancies with bone scan is one of the most common studies in nuclear medicine. unfortunately the conventional planar bone scan has a very low specificity for differentiating benign from malignant lesions especially in the spinal column. in this study, we compared the specificity of spect imaging and conventional planar bone scan. we studi...

This study was undertaken to examine the ability of SPECT in differentiation of a pulmonary lesion suspecions of lung cancr. A total of 170 patients with suspected lung cancer were studied. A dose of Tl-201 chloride {148-296 MBq) was injected intravenously and tomographic early and delayed scans were obtained at 15 miniutes and 3 hours post injection, respectively. Delayed Tl-201 SPECT vi...

UNLABELLED We prospectively evaluated the contribution of 99mTc-HMPAO SPECT in patients who have sustained acute, mild or moderate head trauma. METHODS Forty-two patients formed the first subgroup of moderate trauma (ModTr) and 25 patients formed the second subgroup of mild trauma (MilTr). All 67 patients underwent an initial SPECT (Tinit) within 4 wk after a closed cranial trauma. After a me...

AIMS To determine in a multicentre, multivendor trial the diagnostic performance for perfusion-cardiac magnetic resonance (perfusion-CMR) in comparison with coronary X-ray angiography (CXA) and single-photon emission computed tomography (SPECT). METHODS AND RESULTS Of 241 eligible patients from 18 centres, 234 were randomly dosed with 0.01, 0.025, 0.05, 0.075, or 0.1 mmol/kg Gd-DTPA-BMA (Omni...
