Case 5/2017 - A 28-Year-Old Woman with Cor Pulmonale Due to Pulmonary Hypertension Secondary to Chronic Pulmonary Thromboembolism

Her technetium-99m diethylenetriaminepentaacetic acid (99mTc-DTPA) radioaerosol inhalation lung scintigraphy (May 21, 2008) revealed marked hypoventilation of the left lung and retention of the radiotracer in the right peri-hilar region, suggestive of a parenchymal process. The use of 99mTC human albumin macroaggregates (99mTC MAA) revealed no perfusion in the left lung and perfusion defects in...

188Re radiopharmaceuticals for radiosynovectomy: evaluation and comparison of tin colloid, hydroxyapatite and tin-ferric hydroxide macroaggregates

BACKGROUND: Radiosynovectomy is a therapy used to relieve pain and inflammation from rheumatoid arthritis and related diseases. In this study three 188Re particulate compounds were characterized according to their physico-chemical properties and their biological behavior in rabbits. The results were compared in order to establish which was the radiopharmaceutical that better fits the requiremen...

Hydroxide: A First Experience

Radiation synovectomy (RS) is indicated when conventional pharmacologic treatment of chronic synovitis has not relieved its symptoms. The use of radionuclides that are bound to ferric hydroxide (FH) particles has been shown to be effective and safe for this procedure. 166Ho-FH macroaggregates offer promising properties for RS but there is a lack of clinical data. We investigated the efficacy an...
