MRI evaluation of pituitary macroadenomas tumor consistency
摘要
Abstract
Objective: To assess the role of the preoperative MR signal in predicting the tumor consistency of pituitary macroadenomas. Materials and Methods:According to the surgical findings, 120 pituitary macroadenomas were divided into three types: hard, soft and mixed type. Patient's age, maximum diameter of tumor, the ratios of signal intensity of tumor to the white matter of temporal lobe in solid tumors were compared in different types. Surgical approach and resection degree in three types tumors were analyzed comparatively. Categorical variables were examined with the chi-square; continuous-scale data were analyzed with the analysis of variance. Results: 12 of 13 non-solid tumors were soft. All non-solid tumors received total or subtotal transsphenoidal hypophysectomy. In 107 solid tumors, the ratios of T2-weighted signal intensity of tumors to the white matter of temporal lobe in soft type was higher than other types (P=0.005, 0.000, respectively). Resection degree of soft tumors was higher than hard tumors (χ2=14.13, P=0.003). Conclusion: The ratios of T2-weighted signal intensity of pituitary macroadenomas to the white matter can be used as an indicator to preoperatively assess the consistency of pituitary tumors, which can help to find the appropriate surgical approach.关键词
