RESUMO

OBJECTIVE: To explore the features of obturator nerve (ON) by high-resolution CT (HRCT) at the same slice with multiplanar planar reconstruction techniques and clinic value thereof. METHODS: The normal lumbar vertebral bodies of 60 healthy adults and the abnormal lumbar vertebral bodies of 31 patients with ON disorders were scanned with 16-slice spiral CT, multiplanar reconstruction was conducted in the Workstation ADW4. 1, with UNIX system and DICOM form. The images at the same slice were studied. RESULTS: The shapes, thickness, direction, length, adjourning relationship, and tension could be shown at the same slice of oblique and coronal section or oblique and sagittal plane with rotation in external sides on the way from the starting point of dural sac to foramen obturatum in pelvis, meanwhile the manifestations of abnormal ON also could be shown. CONCLUSION: The anatomical features and abnormal manifestation of ON at the same slice with 16-slice spiral CT using the multiplanar reconstruction techniques can be fully shown from the starting point of dural sac to the foramen obturatum in pelvis. This technique is very important in diagnosis and treatment of diseases of obturator nerve.

RESUMO

OBJECTIVE: To explore value of multiplanar reconstruction of lumbar nerve roots on the same level by high resolution computed tomography (HRCT) in diagnosis of lumbar disc herniation and/or bulge (LDHB). METHODS: Thirty-one patients with manifestations of typical nerve root compression, such as lumbago and tenderness of percussion pain at the corresponding sites were scanned with 16-slice spiral CT and multiplanar reconstruction of lumbar nerve roots on the same level with the workshop ADW4.150, and were diagnosed as with LDHB with 50 segments. The diagnoses were confirmed by operation later. RESULTS: This technique showed not only the existence of LDHB but also the signs of nerve root compression, including the touch of nerve roots with the LDHB (100%), translocation of nerve roots (96%), morphological change (94%), changes of diameter (92%), changes of direction (88%), changes of density (80%), increase of the angle between the dural sac and nerve root (76%), etc. Along with the prolonging of time, the nerve roots became thinner in all segments. CONCLUSION: Multiplanar reconstruction of lumbar nerve roots on the same level by high resolution computed tomography is valuable in the diagnosis of lumbar disc herniation and/or bulge.

RESUMO

OBJECTIVE: From November 24 to December 10, 2013, the Chinese People's Liberation Army Navy [PLA(N)] hospital ship Peace Ark was deployed to the Leyte Gulf in the Philippines to provide humanitarian medical relief in Tacloban after Typhoon Haiyan. The purpose of this study was to assess the radiological services aboard the ship to provide guidance for future missions. METHODS: A retrospective review was performed on a cohort of 109 patients who underwent digital radiography (DR) and 59 patients who underwent computed tomography (CT) scans during a 16-day period during a humanitarian medical relief mission to the Philippines. Patient demographics, DR findings, and CT findings were analyzed. RESULTS: The mean age of the 109 DR patients was 39.7 years for the 64 males and 43.7 years for the 45 females. A total of 148 DR examinations were performed of the chest (n=109), extremities (n=35), and spine (n=4). The mean age of the 59 CT patients was 43.8 years for the 32 males and 49.1 years for the 27 females. A total of 72 CT scans were performed of the head and neck (n=36), thorax (n=24), abdomen (n=5), spine (n=4), and extremities (n=3). The imaging findings mainly included disaster-related and non-disaster-related fractures, pulmonary tuberculosis, pulmonary infection, acute brain infarction, intracranial hematoma, and occupying lesions. CONCLUSION: Analysis of radiological services during a humanitarian medical relief mission to the Philippines provided meaningful information for future humanitarian medical relief missions.
