Chordoma of petrosal mastoid region: A case report.

Background: Chordoma is a rare low-grade malignant tumor originating from embryonic notochordal tissue mainly occurring in the axial bone, mostly in the spheno-occipital junction and sacrococcyx, which accounts for approximately 1% of all malignant bone tumors and 0.1%-0.2% of intracranial tumors.

Influences of scan-position on clinical ultra-high-resolution CT scanning: a preliminary study.

The aim of this study is to access influences of scan-position on clinical ultra-high-resolution CT scanning. We proposed a breath-hold assisted ultra-high-resolution scanning technology (scan scheme G) and compared with scan scheme A (regular CT plain scan) and scheme B (1024 ultra-high-resolution scan with patients stay in supine position). A total of 30 patients with fGGO were included in this study.

Prognostic value of high-resolution magnetic resonance imaging in evaluating carotid atherosclerotic plaque in patients with ischemic stroke.

Background: Ischemic stroke (IS) is a devastating occurrence affecting millions worldwide. This study aimed to evaluate the prognostic value of high-resolution magnetic resonance imaging (HRMRI) in assessing carotid atherosclerotic plaque in IS patients.

Methods: Between January 2013 and March 2015, 338 IS patients were recruited for the investigative purposes of the study.

Posaconazole vs. fluconazole as invasive fungal infection prophylaxis in China: a multicenter, randomized, open-label study.

Background: Invasive fungal infection (IFI) is common in neutropenic patients with acute myelogenous leukemia (AML) or myelodysplastic syndrome (MDS). Posaconazole is a broad-spectrum triazole antifungal drug with efficacy in prevention of IFI; however, it has not been previously studied as prophylaxis in a Chinese population.

Methods: This multicenter, randomized study in China enrolled AML and MDS patients with persistent chemotherapy-induced neutropenia.

[Lower limb hemodynamic evaluation in patients with diabetic foot using 99mTc-methylene diphosphonate three-phase bone scintigraphy].

Objective: To evaluate the efficacy of (99m)Tc-methylene diphosphonate (MDP) bone scintigraphy in diagnosis of diabetic foot.

Methods: (99m)Tc-MDP three-phase bone imaging was performed in 56 patients with diabetic foot and 36 non-diabetic control subjects, each foot was analyzed independently. The radioactive concentration per pixel hence the foot to tibia ratio (R(m/t)) was calculated and the time-radioactivity curve of each region of interest generated.
