Comparative StudyHybrid SPECT-CT for characterizing isolated vertebral lesions observed by bone scintigraphy: comparison with planar scintigraphy, SPECT, and CT.
We aimed to assess the role of single photon emission computed tomography-computed tomography (SPECT-CT) for characterizing isolated vertebral lesions observed by bone scintigraphy compared to planar scintigraphy, SPECT, and CT, and to evaluate the impact of SPECT-CT on patient management. ⋯ SPECT-CT is better than planar scintigraphy and SPECT alone, but not CT alone, for characterizing equivocal vertebral lesions that are observed by bone scintigraphy, thus SPECT-CT can have a significant impact on patient management.

Case ReportsSecondary aortoesophageal fistula after thoracic endovascular aortic repair for a huge aneurysm.
Thoracic endovascular aortic repair for a descending thoracic aortic aneurysm is an excellent alternative to open surgery, especially in patients with a number of comorbidities. It may cause fatal complications, including aortoesophageal fistula, but these are very rare. Here, we report the case of secondary aortoesophageal fistula four months after the procedure for a huge descending thoracic aortic aneurysm, which presented with new-onset high-grade fever accompanied by elevated inflammatory markers.

Can diffusion-weighted MRI determine complete responders after neoadjuvant chemoradiation for locally advanced rectal cancer?
We aimed to prospectively determine if analyzing pre- and post-chemoradiotheraphy (CRT) changes in the signal intensity (SI) and apperent diffusion coefficient (ADC) values from diffusion-weighted magnetic resonance imaging (DW-MRI) can accurately predict complete responders for locally advanced rectal cancer. ⋯ In re-staging of rectal tumors by DW-MRI, an increase in ADC values and decrease in SIs can predict therapy response but cannot unequivocally determine a complete response.

Association of pulmonary artery obstruction index with elevated heart-type fatty acid binding protein and short-term mortality in patients with pulmonary embolism at intermediate risk.
Heart-type fatty acid binding protein (H-FABP) is a sensitive marker of myocardial injury and predictor of worse prognosis in patients with pulmonary embolism (PE). Assessment of right ventricular dysfunction and pulmonary artery obstruction index (PAOI) with computed tomography (CT) has been reported as a predictor of mortality in PE. Therefore, we aimed to assess the correlation between H-FABP and CT angiographic PAOI in PE patients at intermediate risk. ⋯ Although H-FABP positivity confers a bad prognosis on PE patients at intermediate risk, PAOI did not predict mortality in this group.
