Objectives: We have previously shown that patterns of splenic arterial enhancement on computed tomography scan change following liver transplantation. We suggested that this is related to changes in portal venous pressure. The aim of this study was to see if similar patterns occur in patients with and without portal hypertension and in patients before and after portal systemic shunts (transjugular portosystemic shunts). Methods: We evaluated contrast enhanced computed tomography scans in patients being evaluated for liver disease and compared those from patients with and without portal hypertension. In addition we eva...

Conclusions L-SURmax showed the most powerful predictive performance than the other PET parameters in predicting occult lymph node metastasis. The combination of three independent risk factors (carcinoembryonic antigen, cytokeratin 19 fragment, and L-SURmax) can effectively predict occult lymph node metastasis in clinical N0 non–small cell lung cancer patients.

Conclusion Semi-quantitative F-18 FDG PET parameters (SUVmax, MTV and T/L) were found to be significantly correlated with Fuhrman grade in patients with RCC and are important markers for differentiation between low- and high-grade tumors. Furthermore, forced diuresis had no incremental value in characterization of primary RCC lesions.

Abstract Pneumocystis jirovecii pneumonia (PJP) occurs in immunocompromised hosts and is classified as PJP with human immunodeficiency virus (HIV) infection (HIV-PJP) and PJP without HIV infection (non-HIV PJP). Non-HIV PJP rapidly progresses to respiratory failure compared with HIV-PJP possibly due to the difference in immune conditions; namely, the prognosis of non-HIV PJP is worse than that of HIV PJP. However, the diagnosis of non-HIV PJP at the early stage is difficult. Herein, we report a case of severe non-HIV PJP successfully managed with veno-venous extracorporeal membrane oxygenation (V-V ECMO). A 54-yea...

Abstract To observe blood vessels at high contrasts, we constructed a first-generation triple-sensitivity X-ray computed tomography (TS-CT) scanner using a cadmium-telluride (CdTe) detector and a triple-amplifying system. X-ray photons are absorbed by the CdTe crystal, and the electric charges produced by photons are converted into voltages using a current-to-voltage (I-V) amplifier, and the I-V output is amplified by a voltage-to-voltage (V-V) amplifier. The V-V output 1 is sent to a dual V-V amplifier through a 5.0-m-length coaxial cable and amplified to two-different outputs of 2 and 3. The three outputs 1-3 ar...

Identifying coronary artery disease (CAD) in atrial fibrillation (AF) patients improves risk stratification and defines clinical management. However, the value of screening for subclinical CAD with cardiac CT in AF patients is unknown. Between 2011 and 2015 94 consecutive patients without known or suspected CAD (66 (57 –73) years, 68% male), who were referred for AF evaluation, underwent a non-contrast-enhanced coronary calcium scan and a coronary computed tomography angiography (CCTA) at our center.

AbstractChronic rhinosinusitis (CRS) significantly affect the quality of life (QoL) of patients. The study was conducted in CRS patients who were treated with functional endoscopic sinus surgery (FESS) after failure of medical treatment to analyze clinical outcome using prospectively collected data through a symptom-based rhinosinusitis outcome measure, the Sino-nasal Outcome Test-22 (SNOT-22). The aim of the study was to evaluate and compare the QoL in patients of chronic rhinosinusitis pre-operative and after FESS by SNOT-22. The prospective study was conducted on 40 patients of chronic rhinosinusitis with or without nas...
