Gadolinium ethoxybenzyl-diethylenetriaminepentaacetic acid (Gd-EOB-DTPA) is a hepatocyte-specific MRI contrast agent. Because the hepatic uptake of Gd-EOB-DTPA depends on the integrity of the hepatocyte mass, this uptake can be quantified to assess liver function. We report the relationship between the extent of Gd-EOB-DTPA uptake and the degree of liver fibrosis. T1-weighted volume-interpolate...

results indicate that after the injection of MSH(4-10)DTPA-l “In, radioactivity is eliminated from the blood with a physiological half-life of 0.19 h. This compares with 1 1 h for bisMSH-DTPA injected by the same route IS]. As a consequence of this rapid elimination, tumour radioactivity was well differentiated from the background by 4 h and at this time, the mean tumour/blood ratio was 10.6 f ...

Primary hepatic angiosarcoma is the most common malignant mesenchymal tumor of the liver. It has a poor prognosis and various appearances on magnetic resonance (MR) images. We report a case of hepatic angiosarcoma with a characteristic appearance on gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced MR imaging in the hepatobiliary phase. A 72-year-old man was adm...

This study evaluated the feasibility of using Te-pentetic acid (DTPA) as a radioactive tracer for aerosolized synthetic surfactant (DPFC, cetyl alcohol, tyloxapol). The “Tc-DTPA was admixed with surfactant and aerosolized using a nebulizer system interfaced to a ventilator with a cascade impactor attached to the endotracheal tube. Particle size distribution for DPPC, cetyl alcohol, and ‘Tc-DTPA...

OBJECTIVE Combination vaccines simplify vaccine administration and have the potential to promote compliance and cost-effectiveness by decreasing the number of injections needed to immunize a child. The objective of this study was to assess the safety and reactogenicity of the diphtheria-tetanus toxoid-acellular pertussis-hepatitis B virus-inactivated polio virus (DTPa-HBV-IPV) vaccine when coad...

Material and methods: 125 patients (IDDM:10, NIDM:115), including 62 men, ages 18-84 years, were studied. In all cases GF (Cr 51 EDTA), ERPF (I-hippuran), kidney split function (obtained from the mTc-MAG3 renogram) and basal serum creatinine (SC) were evaluated at the beginning of the study and patients were clinically followed up for 5 years by SC. Ultrasound and/or intravenous digital angiogr...

INTRODUCTION The crucial moment of Ca-DTPA (calcium salt-diethylenetriaminepentaacetic acid) therapy for the removal of inhaled plutonium is the timing of the first injection. This is because DTPA acts on plutonium while it is in the blood, this action is lost after plutonium has been deposited into the organs. It is, therefore, generally accepted that chelation therapy should be started as ear...

In 14 patients with the diagnosis of glioblastoma (n = 7) or intracranial metastases (n = 7), magnetic resonance (MR) imaging was performed using a variety of spin-echo (SE) pulse sequences before and after intravenous injection of 0.1 mmol gadolinium-DTPA (Gd-DTPA) per kilogram of body weight. In 10 patients, tumor tissue could not be adequately differentiated from perifocal edema on unenhance...

BACKGROUND Alpha-particle emitting isotopes are effective novel tools in cancer therapy, but targeted delivery into tumors is a prerequisite of their application to avoid toxic side effects. Peritoneal carcinomatosis is a widespread dissemination of tumors throughout the peritoneal cavity. As peritoneal carcinomatosis is fatal in most cases, novel therapies are needed. F3 is a tumor homing pept...

Purpose: To elucidate MRI features of primary hepatic mucosa-associated lymphoid tissue (MALT) lymphoma, particularly, the “speckled enhancement” on gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced MRI.
