[The scintigraphic assessment of the patients suffering from cardia achalasia, treated by pneumatic dilatation].

The esophageal scintigraphy is a technique used to evaluate the motility and the clearance of the esophagus. The patients with achalasia of the cardia were evaluated, before treating them with pneumatic dilatation and after. The reason is to evaluate the efficiency of the pneumatic dilatation technique in the treatment of esophageal achalasia. The pneumatic dilatation with an instrument type Rigiflex is a well/handled and used technique in our clinic. In the study 22 patients were included and we had in view the esophageal transit time and the residuary radioactivity before and after the pneumatic dilatation. We established an important statistical improvement of the data obtained after the dilatation comparative with the data before the treatment (p < 0.01).

[Sequential esophageal scintigraphy contribution on cardia achalasia diagnosis].

Achalasia is a mortality disorder described in 1674 by Willis. It has a small incidence in the general population. The main symptom is dysphagia. The golden standard for diagnosis is esophageal manometry. Esophageal scintigraphy is a non-invasive method of exploration: the technique is simple, it lasts five minutes and is more sensitive than the radiologic exam. The esophageal scintigraphy was made in the Nuclear Medicine Laboratory of the Sf. Spiridon Hospital using a gamma scann Diacam--Siemens. The parameters measured with esophageal scintigraphy are: esophageal transit time, residuary radioactivity. Our study included a number of 37 patients with achalasia with ages between 16 and 80 years (the average--47, 3 years). Our conclusions are the same with the data from literature.

[Multiple perfusion defects detected by scintigraphy].

Pulmonary embolism is a cause of death and the most common pathological condition involving the lungs of hospitalized patients. Early detection can rise prognosis of survival. In this case presented below, a patient suspected of pulmonary embolism was sent to our department, for assessing the lung perfusion, performing the pulmonary perfusion scintigram with 99mTc-MAA for establishing a diagnosis. Lung imaging is a noninvasive technique without patient discomfort that objectively can depict the distribution of the radiopharmaceutical throughout the lungs. We conclude that multiple non segmental defects with no radiological abnormalities state that the probability of pulmonary embolism is lower than 20%.

Image processing in myocardial SPECT acquisition.

Image processing for the imagistic medicine domain nuclear medicine have long time being realised through specifical protocols which rarely allowed the intervention of other informatical modalities. Processing depends first of all on the acquisition type. This paper presents the steps of one of the most complex image processing protocols, in the case of myocardial SPECT acquisition (Single Photon Emission Computed Tomography).
