Computed tomography in the diagnosis of steroidal hepatopathy in a dog: case re...
Oliveira,D.C; Costa,L.A.V.S; Lopes,B.F; Lanis,A.B; Borlini,D.C; Maia Júnior,J.A; Costa,F.SIt is reported a case of an eight-year-old Yorkshire Terrier dog, with a history of prolonged use of prednisone in a dosage of 1mg/kg of body weight each 24 hours during two years. The helical computed tomography revealed hepatomegaly associated to a hyperattenuation of the parenchyma, with a radiodensity value of 82.55 Hounsfield units (HU). The spleen presented a mean radiodensity of 57.17HU, and a radiodensi...
Hb H disease resulting from the association of an αº-thalassemia allele [-...
Kimura,Elza M.; Oliveira,Denise M.; Fertrin,Kleber; Pinheiro,Valéria R.; Jorge,Susan E.D.C.; Costa,Fernando F.; Sonati,Maria de FátimaHb H Disease is caused by the loss or inactivation of three of the four functional a-globin genes. Patients present chronic hemolytic anemia and splenomegaly. In some cases, occasional blood transfusions are required. Deletions are the main cause of this type of thalassemia (α-thalassemia). We describe here an unusual case of Hb H disease caused by the combination of a common αº deletion [-(α)20....
Respiratory movements cause significant misregistration and altered SUVs in tho...
D. Faria; J. Patrina; A. Sevilla; J. Tavares; L. Ribeiro; D. Sousa; J. Oliveira; J. Vale; D. C. CostaPET-CT with 18F-DG studies are frequently used in the management of patients with lung malignancies. Unfortunately respiratory movements may influence significantly disease evaluation, particularly during longitudinal follow-up. Our aim is to investigate the influence of forced inspiration (I) and expiration (E) on shallow breathing (S) results (anatomic registration and SUV calculation). We included 18 patient...
