Abstract:
The radial scar (RS) or complex sclerosing lesion (CSL) of the breast represents a management dilemma on diagnosis at breast core needle biopsy because of the risk of associated malignancy identified only upon surgical excision. To determine our experience, we retrospectively reviewed core needle biopsies performed at the Darlene G. Cass Breast Imaging Center from 2006 to 2011, identifying 67 patients with RS or CSL, and correlated histology at excisional biopsy with core biopsy results. Of the 67 cases, 6 (9%) were associated with malignancy at surgical excision. The average size of the RS or CSL was 1.42 cm. In conclusion, RS or CSL diagnosed at core needle biopsy still warrants surgical excision because of the significant percentage (9%) of cases with associated malignancy.

01:25Assessment of apical radial pulse
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

01:11Assessment of radial pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

In a radial system with a fault downstream of the third breaker, ideally, only the third breaker will open, isolating the fault and interrupting the load connected beyond it. The second breaker has a longer delay setting,...
01:11Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...
