Contrast-enhanced magnetic resonance imaging with a novel nano-size contrast agent for the clinical diagnosis of patients with lung cancer.

Recent studies have indicated that magnetic resonance imaging (MRI) efficiently diagnoses lung cancer. However, the efficacy of MRI in diagnosing lung cancer requires improving for patients in the early stage of the disease. In the present study, a novel nano-sized contrast agent of chistosan/FeO-enclosed bispecific antibodies (BsAbCENS) was introduced, which targeted carcino-embryonic antigen (CEA) and neuron-specific enolase (NSE) in lung cancer cells.

Colonic Metastasis From Esophageal Squamous Cell Carcinoma Demonstrated With 18F-FDG PET/CT.

Metastatic involvement of the colon is extremely rare. We report a 63-year-old man with colonic metastasis from esophageal squamous cell carcinoma. Whole-body F-FDG PET/CT showed abnormal tracer uptakes in the sigmoid colon, which was subsequently confirmed as metastatic from esophageal squamous cell carcinoma.

Characteristics of elastofibroma dorsi on PET/CT imaging with (18)F-FDG.

Purpose: To assess the characteristics of 18F-FDG uptake in elastofibroma dorsi (EFD).

Methods: Seventeen patients with EFD were retrospectively studied.

Results: The mean±S.

Myofibroma of the Left Supraspinous Muscle on 18F-FDG PET/CT.

Myofibroma of the muscle is extremely rare. This report describes a 46-year-old man with myofibroma of the left supraspinous muscle on 18F-FDG PET/CT and includes MRI and 18F-FDG PET/CT findings. Whole-body 18F-FDG PET/CT showed abnormal tracer uptakes in the left supraspinous muscle, which was subsequently confirmed as myofibroma by histopathology.

18F-FDG PET/CT Findings of Metastasis to Spongy Body of Penis From Urothelial Carcinoma of Bladder.

The spongy body of the penis metastasis from other primary sites is a rare clinical entity. It is frequently associated with widespread metastatic disease and poor prognosis clinically. We report a case of a 61-year-old man with a previous history of cystectomy due to infiltrating urothelial carcinoma of the bladder 12 months ago and presented with penile shaft swelling pain and hematuria for 3 months.

Metastatic Malignant Fibrous Histiocytoma in the Stomach: Imaging With 18F-FDG PET/CT.

Metastatic malignant fibrous histiocytoma (MFH) in the stomach is extremely rare. We report a 73-year-old man with MFH in the left popliteal fossa that metastasized to the stomach. Whole-body F-FDG PET/CT showed abnormal tracer uptakes in the stomach, which was subsequently confirmed as metastatic MFH.

Feasible Method to enable clear visualization of suspected bladder cancer with 18F-FDG PET/CT.

Purpose: To evaluate value of a new method in detecting bladder lesion with (18)F-FDG PET/CT.

Methods: Routine and delayed scans of 14 patients were retrospectively studied. All these bladder lesions were confirmed by pathology.

[Clinical value of (18)F-FDGPET/CT in differentiation between benign lesions and lung cancer for large shadows in patients with pneumoconiosis].

Objective: To evaluate the clinical value of (18)F-FDG PET/CT in the differentiation between benign lesions and lung cancer for large shadows in patients with pneumoconiosis.

Methods: A retrospective study was conducted in 21 patients with a confirmed diagnosis of pneumoconiosis who had a total of 37 large shadows in the lung fields as shown by whole-body (18)F-FDG PET/CT imaging, and (18)F-FDG uptake was evaluated using the maximum standardized uptake value (SUVmax). Twelve lesions were examined by CT-guided aspiration biopsy, and one case underwent fiberoptic bronchoscopy, as well as tests based on bronchoalveolar lavage fluid and sputum; the other cases were followed up for more than 2 years.
