FDG PET is more accurate than is CT or ES for evaluating metastasis to individual lymph node groups and for N staging in esophageal cancer and thus may be helpful in determining the therapeutic plan.

Both virtual reality rehabilitation and conventional occupational therapy were effective for upper-limb training. Virtual reality training was superior in improving dexterity, performance of activities of daily living, and active forearm supination motion. The effect of virtual reality training was significant in children with more severe motor impairments.

Arterial and venous endothelial cells exhibit distinct molecular characteristics at early developmental stages. These lineage-specific molecular programs are instructive to the development of distinct vascular architectures and physiological conditions of arteries and veins, but their roles in angiogenesis remain unexplored. Here, we show that the caudal vein plexus in zebrafish forms by endothelial cell sprouting, migration and anastomosis, providing a venous-specific angiogenesis model. Using

Even though the MR imaging findings of ependymomas vary and are nonspecific, awareness of these findings, and of tumor distribution according to age, is helpful and increases the likelihood of correct preoperative clinical diagnosis.

Optimal parameters for DTI in the cervical spinal cord included a b-value of 900 seconds/mm, 15 diffusion gradient directions, 5 excitations, and a slice thickness of 4mm.

PMMRL lesions are commonly detected in symptomatic patients. We have introduced an MRI classification system. PMMRL lesions are significantly associated with age, medial meniscal tears, medial meniscal extrusion, insertional PMMRL osseous change, regional synovitis, osteoarthritis, insufficiency fracture, and cruciate ligament degeneration.

We could quantitatively measure the metal artifact volume in MDCT by using 3D imaging software. In practice, the results of our study indicate that increasing kilovoltage is more effective for metal artifact reduction than increasing the effective mAs.

The results of this randomized controlled study support the use of ISE for enhancing pulmonary function and breath control for speech production in children with CP.

This study investigates the developmental outcomes of preterm children according to severity of periventricular leukomalacia. One hundred preterm children with periventricular leukomalacia evident on brain magnetic resonance imaging and who had undergone neuropsychologic evaluation were selected. Intellectual disability was noted in 27.8% of the children with mild periventricular leukomalacia, 53.2% with moderate periventricular leukomalacia, and 77.1% with severe periventricular leukomalacia. T

Very strong relationships were noted among three communication classification systems that are closely related with intellectual ability. Compared to gross motor function, manual ability seemed more closely related with communication function in these children.

Serial sonography after arthroscopic rotator cuff repair was useful for monitoring the postoperative changes in a repaired tendon. The morphologic appearance of the repaired tendon and peritendinous soft tissue changes improved over time and nearly normalized within 6 months of surgery.
