Comparison of NaI(T1), CdTe, and HgI2 surgical probes: effect of scatter compensation on probe performance

Autor: D P, Kwo, H B, Barber, H H, Barrett, T S, Hickernell, J M, Woolfenden

Publikováno v: Medical physics. 18(3)

Spatial variation in the background source distribution makes tumor detection difficult for single-detector probes. Using a single energy window that brackets the photopeak helps discriminate against background events dominated by Compton scattering.

Comparison of NaI(Tl), CdTe, and HgI2 surgical probes: physical characterization

Autor: H B, Barber, H H, Barrett, T S, Hickernell, D P, Kwo, J M, Woolfenden, G, Entine, C, Ortale Baccash

Publikováno v: Medical physics. 18(3)

The physical properties of three surgical probes containing different radiation detectors are compared: a NaI(Tl) scintillator with a flexible, fiber-optic light guide, and two semiconductor detectors that operate at room temperature, CdTe and HgI2.

Acquired immunodeficiency syndrome: Ga-67 citrate imaging

Autor: James H. Shelhamer, J T Simmons, J M Woolfenden, Steven M. Larson, Phillip D. Smith, Frederick P. Ognibene, Jorge A. Carrasquillo, Henry Masur

Publikováno v: Radiology. 162:383-387

All gallium-67 citrate scans obtained in patients with acquired immunodeficiency syndrome (AIDS) at the Clinical Center, National Institutes of Health (Bethesda, Md.) were retrospectively analyzed and correlated with the results of bronchoscopy, ches

Detection of small radiation sources: the effect of mode of count-rate presentation

Autor: M C, Borgstrom, H B, Barber, J M, Woolfenden, G W, Seeley, J L, Warren

Publikováno v: Medical physics. 15(2)

We used an observer-performance study to compare four different modes of presenting count-rate data from a radiation detector. Observers searched for small, concealed radioactive sources using a hand-held radiation-detector probe. The modes of count-

Circulatory control of splenic hyperfunction in children with peripheral blood dyscrasia

Autor: C L, Witte, J J, Corrigan, M H, Witte, D B, Van Wyck, R E, O'Mara, J M, Woolfenden

Publikováno v: Surgery, gynecologyobstetrics. 150(1)

Ligation of the splenic artery was performed upon six children with a variety of peripheral cytopenias associated with hypersplenism to decrease splenic hyperfunction while preserving some splenic tissue. While this procedure initially improved the p

Evaluation of carcinoma of the cervix using 111In-bleomycin

Autor: J M, Woolfenden, A D, Waxman, P J, Disaia, J K, Siemsen

Publikováno v: Obstetrics and gynecology. 46(3)

Indium-111 attached to bleomycin is useful in the scintigraphic localization of a variety of tumors. Since it does not normally accumulate in bowel and feces, it is superior to other radiopharmaceuticals, such as gallium-67 citrate, in the demonstrat

Bone scanning in lymphoma

Autor: J P, Schechter, S E, Jones, J M, Woolfenden, D L, Lilien, R E, O'Mara

Publikováno v: Cancer. 38(3)

The results of bone scanning with the newer technetium-99m complexes were correlated with clinical, laboratory, and radiographic findings in 26 patients with malignant lymphoma (10 with Hodgkin's disease and 16 with non-Hodgkin's lymphomas). Abnormal

Evaluation of the cardiac effects of doxorubicin by serial echocardiography

Autor: J J, Hutter, D J, Sahn, J M, Woolfenden, Y, Carnahan

Publikováno v: American journal of diseases of children (1960). 135(7)

• Serial echocardiographic studies were performed on 48 children who received chemotherapy with doxorubicin hydrochloride (Adriamycin). For the group as a whole, no correlation could be made between the cumulative dose of doxorubicin administered a

Splenic salvage quantified by uptake of heat-damaged radiolabeled red blood cells. Experimental and clinical studies

Autor: C L, Witte, M H, Witte, G C, McNeill, J N, Hall, G P, Van der Werf, J M, Woolfenden

Publikováno v: American journal of surgery. 155(2)

We evaluated a noninvasive radionuclide technique to quantify splenic trapping function, which is a key step in the disposition of blood-borne particulates such as poorly opsonized encapsulated microorganisms implicated in hyposplenic fulminant sepsi
