This study was designed to investigate the potential role of radionuclide angiographic phase imaging in defining ventricular pacing sites. Twenty patients were paced from multiple right ventricular and left ventricular sites. Ten patients had both normal wall motion and normal electrocardiograms (ECGs), while 10 patients had segmental wall motion abnormalities and/or bundle branch block. Both c...
Early detection of chronic obstructive pulmonary disease using radionuclide lung-imaging procedures.
One hundred subjects answered a respiratory questionnaire and underwent a physical examination, tests of pulmonary function, and three radionuclide lung-imaging procedures. The results of the radionuclide procedures were compared with each other and with pulmonary function tests and other diagnostic findings to determine their relative sensitivity for detecting evidence of early obstructive air...
Molecular imaging is a multimodality discipline for noninvasively visualizing biologic processes at the subcellular level. Clinical applications of radionuclide-based molecular imaging for breast cancer continue to evolve. Whole-body imaging, with scintimammography and PET, and newer dedicated breast imaging systems are reviewed. The potential clinical indications and the challenges of implemen...
N uclear medicine plays an important role in the evaluation of inflammation and infection. Radionuclide imaging is complementary to CT in the postoperative patient and is used to help differentiate postoperative changes from infection. In the case of painful joint replacement, radionuclide studies are the primary diagnostic imaging modality for differentiating infection from other causes of pro...
The features of Hypertrophic pulmunary osteoarthropathy (HPOA) on radionuclide bone scintigraphy have been well described in case reports and small series of patients. The aim of this study was to investigate prospectively the prevalence and distribution of HPOA in a large series of patients with carcinoma of the lung. Two hundred and eleven patients aged 31-89 years (average age 66 years...
Since the development of gated SPECT imaging approximately 10 y ago, this technique is now almost universally used as an adjunct for radionuclide perfusion imaging, enabling the assessment of perfusion along with determination of regional and global left ventricular function in the same examination. The gated SPECT determination of the left ventricular ejection fraction and volumes has been ext...
Epilepsy is one of the most common yet diverse neurologic disorders, affecting almost 1%-2% of the population. Presently, radionuclide imaging such as PET and SPECT is not used in the primary diagnosis or evaluation of recent-onset epilepsy. However, it can play a unique and important role in certain specific situations, such as in noninvasive presurgical localization of epileptogenic brain reg...
