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 ...

Aim: Assess the role of hybrid modality SPECT/CT versus planar scintigraphy in sentinel lymph node (SLN) identification patients with breast cancer. Methods: Planar and were performed 23 women cancer (mean age 59.5 years range 25 - 82 years) invasive (T0, T1 T2), without clinical evidence axillary metastases (N0) no remote (M0), radiocolloid was injected four subareolar sites. images separately...

Introduction: Patients with essential tremor (ET) have 3.5 times greater risk of developing Parkinson's disease (PD) throughout their lives, also known as PD antecedent ET (ET-PD). Single photon emission computed tomography radiotracer imaging dopamine transporters (TRODAT-SPECT) can help differentiate these two diseases. Method: Relate the results TRODAT-SPECT in patients to potential progress...

Background: Hairline rib fracture commonly happens after blunt trauma, and it is hard to be detected by X-ray. Many methods can used, among them, the hybrid image of single-photon emission computed tomography (SPECT) (CT) seems produce higher sensitivity for diagnosis. Case presentation: A 63-year-old man came our rehabilitation clinic a vehicle accident 25 days earlier. He had multiple plain f...

Introduction: It is a common protocol to use 201Tl for the rest and 99mTc for the stress cardiac SPECT imaging. Theoretically, both types of imaging may be performed simultaneously using different energy windows for each radionuclide. However, a potential limitation is the cross-contamination of scattered photons from 99mTc and collimator X-rays into the 201Tl energy window. We used a middle en...

Background—The accuracy of exercise echocardiography and Tl single photon emission computed tomography (SPECT) is similar in the diagnosis of coronary artery disease (CAD). However, comparative data on long-term prognosis are lacking. Methods and Results—Clinical variables and exercise, echocardiographic, and Tl tomographic parameters were studied in 248 patients (age, 56612 years [mean6SD]; 18...

The hybrid imaging methodsSingle photon Emission Tomography-Computer Tomography / SPECT-CT / and Positron Emission Tomography-Computer Tomography / PET-CT/ allow receiving of combined image of two different techniques. In such a way it is possible to superimpose detailed anatomical image of the multislice spiral computer tomography with specific and sensitive molecular images of the SPECT and P...

Pre-surgery evaluation, indications for cochlear implantation and expectations in terms of post-operative functional results remain challenging topics in pre-lingually deaf adults. Our study has the purpose of determining the benefits of Single Photon Emission Tomography (SPECT) assessment in pre-surgical evaluation of pre-lingually deaf adults who are candidates for cochlear implantation. In 7...
