The Study of Menstrual and Other Blood Loss, and Consequent Iron Deficiency by Fe$sup 59$ Whole Body Counting

Description: An established method for determining radioiron absorption by whole body counting was used to study six parous women with hypochromic anemia and menorrhagia, and a seventh nulliparous woman with normal blood values and normal menses. In addition to demonstrating iron deficiency by increased radioiron absorption, the method was found useful in estimating the quantity of blood lost with each menstrual period. As much as 550 ml of menstrual loss was noted in two of the patients studied. Estimates … more

Two detector MWPC position camera with honeycomb lead converters for medical imaging: performance and developments

Description: A MWPC camera for Nuclear Medicine imaging with positron emitting isotopes has been built. The two planar detectors are converter coupled MWPC with sensitive area 48 x 48 cm/sup 2/ placed 50 cm apart with clear space in between for the patient. The effective sensitivity of 5.8% for each detector with a spatial resolution of 7 mm FWHM on the image plane is achieved by use of honeycomb lead-on-plastic onverters. Present performance in imaging test objects and in clinical applications is described… more

Absorption and Turnover Rates of Iron Measured by the Whole Body Counter

Description: Human iron metabolism has been extensively studied in the past twenty-five years with the radioisotopes iron⁵⁵ and iron⁵⁹. Before the availability of the whole body counter, however, iron absorption studies were performed by the indirect methods of fecal assay of unabsorbed radioiron, and estimation of red cell incorporation of absorbed tracer. The few long-term excretion studies performed required numerous assumptions, since human iron excretion was less well understood. Whole body counting pr… more

A Note Concerning the "100% Value" in Iron Absorption Studies by Whole Body Counting

Description: The evaluation of iron absorption using a single crystal whole-body counter is complicated by the inherent difficulty of determining a correct "100% value". Shortly after ingestion, tracer radioiron can be found in the stomach, upper small intestine, portal circulation and liver. Fourteen to twenty days later, the time at which absorption is measured most effectively, the radioiron will be distributed between the red cell mass, liver, spleen, bone marrow and other storage areas. With this mixed… more

TWO DETECTOR POSITRON CAMERA WITH HONEYCOMB LEAD CONVERTERS FOR MEDICAL IMAGING: PERFORMANCE AND DEVELOPMENTS

Description: A Multiwire Proportional Chamber (MWPC) camera for Emission Tomography with positron emitting isotopes has been built. The coincident 511 KeV gammas are detected by their interaction with lead-on-plastic honeybomc converters coupled to planar MWPC detectors with sensitive area 48 x 48 cm{sup 2} placed 50 cm apart with clear space in between for the patient. Each detector box has two MWPC: the innermost MWPC are coupled to two converters, while the outer ones have only 1 converter. This configur… more

Cerebral imaging using $sup 68$Ga DTPA and the U.C.S.F. multiwire proportional chamber positron camera

Description: A multiwire proportional chamber positron camera consisting of four 48 x 48 cm$sup 2$ detectors linked to a small digital computer has been designed, constructed, and characterized. Initial clinical application to brain imaging using $sup 68$Ga DTPA in 10 patients with brain tumors is described. Tomographic image reconstruction is accomplished by an algorithm determining the intersection of the annihilation photon paths in planes of interest. Final image processing utilizes uniformity correctio… more

Clinical high-purity germanium gamma-camera

Description: The need in clinical nuclear medicine for imaging devices with high spatial resolution has been discussed at length for many years. More recently, specialists in cardiology and neurology have restated this need for greater resolution in order to effect earlier or more accurate diagnoses of brain tumors, cerebral and myocardial ischemia and infarcts and septum defects, among others. Our approach to filling this need is to ultimately develop a 3072-element, high-purity germanium camera with a 2-m… more
