Two cases of tuberculous mediastinal lymphadenopathy are presented in which the clinical features mimicked those of pulmonary embolism, causing striking abnormalities on radionuclide scintigraphy. It is concluded that tuberculous mediastinal lymphadenopathy should be included in the differential diagnosis of reduced lung perfusion due to proximal pulmonary artery occlusion.

The aim of this study was to determine whether perfusion-scintillation scanning, used as a predictive pre-operative index of lung functionality in patients with lung cancer, is affected by the level of pulmonary blood flow (PBF). Twenty patients with primary lung cancer underwent spirometry and a radionuclide-perfusion scan (macroaggregated albumin particles labelled with 99mTechnetium) both at...

Objectives: Lung scintigraphy is non-diagnostic in most patients suspected of pulmonary embolism when performed in planar mode. Tomographic mode could improve lung scan performance but has not been rigorously assessed. In this study we assessed the usefulness of tomographic mode in patients with a non-diagnostic lung scan scintigraphy. Methods: pulmonary embolism was diagnosed or ruled out in c...

Introduction: The purpose of this study is to assess the integrated role of scintigraphy by Tc99m MIBI in diagnosis of parathyroid adenoma and its impacts on the myocardium, and to evaluate whether myocardium perfusion gated SPECT study could be a complementary routine workup for patient with positive parathyroid adenoma on Tc99m MIBI parathyroid scan. Methods: Rest myocardium perfusion gated ...

  Introduction: The relationship between depression and coronary artery disease is well established; however assessment of this relationship using functional and semi-quantitative imaging (myocardial perfusion scintigraphy) was lacking. The aim of this study was to assess the relationship between the severity of depression and the severity of myocardial perfusion abno...

Lung ventilation-perfusion scintigraphy is of great value for the management of patients with both primary lung disease and heart disease, by proving pathophysiological information of importance for the diagnosis, follow-up and functional evaluation of the patients. Krypton 81m radioactive gas is preferable for pediatric application due to its short half-life. However, the rubidium-krypton 81m ...

Background: The standard treatment for locally advanced non-small cell lung cancer (LA-NSCLC) is represented by concomitant chemo-radiotherapy followed consolidation with durvalumab that ensures a 5-year survival of 46%. However, the risk radiotherapy-induced pneumonia (RIP) almost 10–15%. Complete cardiological examination also usually performed during cardiopulmonary pre-treatment evaluation ...
