[Assessment of flexibility in adolescent idiopathic scoliosis by curved planar reformation using multi-slice spiral CT scanning].

Objective: To investigate the role of curved planar reformation (CPR) using multi-slice spiral CT scanning to evaluate the coronal and sagittal plane in scoliosis so as to affirm the features of supine coronal and sagittal plane in idiopathic scoliosis.

Methods: Thoracic and lumbar spine multi-slice spiral CT scanning was undertaken on 45 patients with adolescent idiopathic scoliosis (AIS), all female, age 10 - 18. CPR was used to reconstruct the spine coronal and sagittal planes respectively.

[Collateral supply in patients with severe carotid stenosis].

Objective: To determine the collateral supply is sufficiency or not in patients with carotid stenosis.

Methods: Fifteen consecutive patients with carotid stenosis underwent carotid endarterectomy (CEA). We evaluated the patent collateral pathways through the anterior and posterior communicating arteries or the ophthalmic artery (ACoA; PCoA; OA) with TCD before CEA.

[Development of a predicting model of survival rates for patients with salivary adenoid cystic carcinoma].

Objective: To establish a predicting model of survival rates and to evaluate the weighted contributions of each key prognostic factor of the patients with salivary adenoid cystic carcinoma (SACC).

Methods: One hundred and eighteen follow-up cases with SACC were analyzed for the survival study with retrospective cohort method. Ten possible clinical and pathologic factors were selected.
