Meanings of directed needle in inglês

The hole was eight feet in diameter, its perimeter clustered with three rows of inwardly- directed needle-sharp teeth.

Purpose: We compared prostate cancer detected in transition zone directed needle biopsies with those in corresponding radical prostatectomy specimens.

Materials and methods: We reviewed needle biopsy and radical prostatectomy slides from 61 patients in whom cancer was present on transition zone directed needle biopsy.

Cancer identified in a left or right transition zone directed needle biopsy did not predict ipsilateral transition zone cancer in almost 50% of cases.
