Direct comparison of choline PET/CT and MRI in the diagnosis of lymph node metastases in patients with prostate cancer.

Background: Lymph node detection in prostate cancer is challenging and critical to determine treatment policy. Choline PET/CT (positron emission tomography/computed tomography) and magnetic resonance imaging (MRI) have been used for the evaluation of lymph node metastasis in patients with prostate cancer for the past decade. However, only limited patients underwent direct comparison studies.

Evaluation of Visceral Adipose Tissue Oxygenation by Blood Oxygen Level-Dependent MRI in Zucker Diabetic Fatty Rats.

Objective: This study aimed to investigate the feasibility of blood oxygen level-dependent magnetic resonance imaging (BOLD-MRI) to evaluate visceral adipose tissue (VAT) oxygenation in Zucker diabetic fatty (ZDF) rats and its associations with systemic metaflammation.

Methods: Five-week-old ZDF rats and Zucker lean (ZL) rats were fed a high-fat diet (HFD) for 18 weeks. A baseline BOLD-MRI scan of perirenal adipose tissue was performed after 8 weeks of HFD feeding, and then the rats were randomized to receive pioglitazone or a vehicle for the following 10 weeks.

[Manifestations of PET/CT Imaging in Primary Central Nervous System Lymphoma].

Objective: To investigate the PET/CT features of primary central nervous system lymphoma(PCNSL).

Methods: A retrospective analysis of PET/CT imaging manifestations and clinical data was performed in 4 PCNSL cases which were confirmed by surgery or stereotactic pathologic biopsy.

Results: The pathologic biopsy in 4 patients all showed diffuse large B cell lymphoma with a total of 8 lesions.

Inflammatory monocyte/macrophage modulation by liposome-entrapped spironolactone ameliorates acute lung injury in mice.

Aim: To examine the therapeutic/preventive potential of liposome-encapsulated spironolactone (SP; Lipo-SP) for acute lung injury (ALI) and fibrosis.

Materials & Methods: Lipo-SP was prepared by the film-ultrasonic method, and physicochemical and pharmacokinetic characterized for oral administration (10 and 20 mg/kg for SP-loaded liposome; 20 mg/kg for free SP) in a mouse model bleomycin-induced ALI.

Results: Lipo-SP enhanced bioavailability of SP with significant amelioration in lung pathology.

Polysplenia Syndrome With Splenic and Skeletal Muscle Metastases From Thyroid Carcinoma Evaluated by FDG PET/CT: Case Report and Literature Review: A Care-Compliant Article.

Polysplenia syndrome (PSS) is a rare congenital abnormality. Metastases to spleen and skeletal muscle from differentiated thyroid cancer (DTC) are also extremely rare. Our case report aims to present an interesting case of PSS associated with splenic metastasis (SM) and skeletal muscle metastasis (SMM) from advanced papillary thyroid carcinoma which was evaluated on fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT).

TrkC expression predicts favorable clinical outcome in invasive ductal carcinoma of breast independent of NT-3 expression.

Background: TrkC, a member of neurotrophin receptor family, functions not only as an oncogene, but also act as a tumor suppressor via a manner of dependence receptor in human malignant tumors. Little is known on the action of TrkC for the clinical prognosis and the progression of breast cancer according to the availability of its ligand NT-3. We sought to investigate the prognostic relevance of NT-3-TrkC axis in breast cancer and estimate its role during the process of breast cancer progression.

[Clinical application of T2*GRE multiple echo sequence on articular cartilage disease in the knee].

Objective: To evaluate the correlation between T2* relaxation time and the pathological changes in the knee joint of patients with osteoarthritis (OA) and analyze the changes of T2* relaxation time in early cartilage injury.

Methods: Sixty-two patients with OA in different phases underwent magnetic resonance imaging (MRI) of the knee and the articular cartilage T2* relaxation time was recorded, with 20 young healthy volunteers as the control group.

Results: Patients with mild OA showed significantly different T2* relaxation time for most of the articular cartilage from that of the healthy volunteers (P<0.

[Magnetic resonance imaging and radiography for diagnosis of lower limb osteosarcoma: a comparative study].

Objective: To investigate the diagnostic value of magnetic resonance imaging (MRI) for lower limb osteosarcoma by comparing the findings between X-ray and MRI.

Methods: Fifteen surgically or pathologically confirmed patients with lower limb osteosarcoma (11 males and 4 females) underwent both plain and enhanced MRI (with CT scanning in 4 cases) in addition to radiography, and the findings were compared.

Results: The diagnostic accuracy of both MRI and X-ray film was 100%.

[Diagnosis of lesions in the major abdominal blood vessels by three-dimensional dynamic contrast-enhanced magnetic resonance angiography].

Objective: To elucidate the working principles of three-dimensional dynamic contrast-enhanced magnetic resonance angiography(3D DCE-MRA)and assess its value in the diagnosis of lesions in the major abdominal blood vessels.

Methods: The imaging data of 3D DCE-MRA and conventional MR examination in 32 cases of suspected major abdominal blood vessel diseases were obtained and analyzed retrospectively.

Results: The peak flow of contrast agents through the abdominal aorta at the level of renal artery occurred 17 to 23 s after the injections.
