Simultaneous 99mTc double labelling of the hepatic reticuloendothelial system and of the red blood cells: a simplified method for the detection of liver hemangiomas.

Sonographic images of liver hemangioma are not specific. Causal detection imposes further investigations (angiography, CT, NMR) which are not always practicable. 99mTc-red blood cells study after 99mTc colloid liver scintigraphy has been already proposed. Ten patients with hepatic hemangiomas were evaluated by simplified, simultaneous in vivo double labelling of the reticuloendothelial system and red blood cells by means of successive i.v. injections of SnCl2, 99mTc colloid albumin and 99mTc-pertechnetate. Focal colloid defects filled with the labelled RBC were revealed in 9/10 liver hemangiomas. Angioscintigraphy showed decreased perfusion and RBC scintigraphy an increased blood volume in the focal colloid defects due to the hemangiomas.

[Gastric transit of a radiolabelled liquid meal in a group of patients with insulin-dependent diabetes mellitus].

The functional alterations in the digestive tract observable during diabetes mellitus are frequent albeit often asymptomatic. They affect several different districts and are still not clearly defined aetiopathogenetically. It was therefore decided to evaluate the gastric transit times of a balanced liquid meal labelled with 99-Tc-colloidal sulphide in a group of patients suffering from insulin-dependent diabetes and in a group of 10 controls. The anatomical integrity of the oesophago-gastro-duodenal tract has been evaluated by endoscopy and histology. Transit times (T/2) proved significantly increased in diabetics (92.38 +/- 33.397 minutes) compared to the controls (48.63 +/- 16.423 minutes), p 0.001. No correlation was observed between gastric transit times, duration of the diabetic disease, degree of glyco-metabolic compensation and presence of autonomous neuropathy.

Long-term follow-up of technetium articular index in rheumatoid arthritis patients during oral chrysotherapy: evidence of paradoxical behaviour.

The Technetium Articular Index (TcAI) is regarded as a parameter of local inflammation in rheumatoid arthritis (RA). We studied TcAI behaviour during 1-year chrysotherapy in a group of fifteen RA patients. In non-responders TcAI showed a gradual decrease up to the 6th month and a return to baseline values within the second semester of the follow-up; conversely, in response patients TcAI remained unchanged during the entire period of the study, thus showing a paradoxical behaviour probably depending on the recovery of normal physical ability and articular activity.
