Three cases with motion artifacts due to body movement were excluded from the images.

Rare Anal Canal Cancer with Secondary Extramammary Paget's Disease (Pagetoid Spread) Complicated by Squamous Cell Carcinoma of the Skin.

A 91-year-old man had a node and erythema in the anal area resistant to treatment. A biopsy of the node in the anus showed atypical cells developing as Paget's disease, and staining revealed that the cells were CK7-positive, CK20-positive, and GCDFP15-negative. Therefore, tumor invasion with pagetoid spread (PS) from the anus to the skin was suspected, and the patient was referred to our department for a close examination and surgical treatment.

Effectiveness of impedance parameters for muscle quality evaluation in healthy men.

We investigated the relationship between impedance parameters and skeletal muscle function in the lower extremities, as well as the effectiveness of impedance parameters in evaluating muscle quality. Lower extremity impedance of 19 healthy men (aged 23-31 years) measured using the direct segmental multi-frequency bioelectrical impedance analysis were arc-optimized using the Cole-Cole model, following which phase angle (PA), [Formula: see text], and β were estimated. Skeletal muscle function was assessed by muscle thickness, muscle intensity, and isometric knee extension force (IKEF).

Transcatheter aortic valve implantation in a patient with severe aortic valve stenosis, colon cancer, and obstructive ileus: A case report.

Virtual endoscopic images by 3D FASE cisternography for neurovascular compression.

Three-dimensional fast asymmetric spin echo (3D FASE) cisternography provides high spatial resolution and excellent contrast as a water image acquisition technique. It is also useful for the evaluation of various anatomical regions. This study investigated the usefulness and limitations of virtual endoscopic images obtained by 3D FASE MR cisternography in the preoperative evaluation of patients with neurovascular compression.

Impedance pharyngography to assess swallowing function.

We evaluated impedance pharyngography (IPG), a new method to assess swallowing function based on changes in the electrical impedance of the neck during swallowing. The electrical impedance of the neck, recorded by the 4-electrode method, changed with the equivalent cross-sectional area of the route of the electric current due to reflex activities of related organs during swallowing. IPG waveforms accurately recorded the swallowing process, therefore.

Magnetic resonance imaging of thoracic epidural venous dilation in Hirayama disease.

Hirayama disease is a nonprogressive, asymmetric amyotrophy of the hands and forearms, possibly caused by compression of the lower cervical cord on neck flexion. The authors used phase-contrast MR angiography to study a patient with this disorder and observed abnormal spinal epidural venous dilation on neck flexion. In addition to mechanical compression of the lower cervical cord, venous congestion in the spinal canal may have a role in promoting anterior horn damage.
