Milan E. J. Pijl, Joost Doornbos, Martin N. J. M. Wasser, Hans C. van Houwelingen, Rob A. E. M. Tollenaar, and Johan L. Bloem: Quantitative Analysis of Focal Masses at MR Imaging: A Plea for Standardization
Since apparently slight changes in the analytic method can result in important numeric changes in calculated metastasis–liver parenchyma signal intensity difference–to-noise ratios, we propose the use of a standardized method for the quantitative analysis of focal masses depicted on MR images that includes an accurate description of the regions of interest.

Michael A. Cohen: Cancer Upgrades at Excisional Biopsy after Diagnosis of Atypical Lobular Hyperplasia or Lobular Carcinoma in Situ at Core-Needle Biopsy: Some Reasons Why
There are several reasons that explain the false-negative core-needle biopsy rate for atypical lobular hyperplasia or lobular carcinoma in situ (LCIS): Some are technical, as in the failure to adequately target the lesion; some are interpretive, as in the misdiagnosis of low-grade solid ductal carcinoma in situ as LCIS; and some are biological, as would occur if a population of LCIS lesions were truly premalignant.

Michael A. Cohen: Cancer Upgrades at Excisional Biopsy after Diagnosis of Atypical Lobular Hyperplasia or Lobular Carcinoma in Situ at Core-Needle Biopsy: Some Reasons Why
There are several reasons that explain the false-negative core-needle biopsy rate for atypical lobular hyperplasia or lobular carcinoma in situ (LCIS): Some are technical, as in the failure to adequately target the lesion; some are interpretive, as in the misdiagnosis of low-grade solid ductal carcinoma in situ as LCIS; and some are biological, as would occur if a population of LCIS lesions were truly premalignant.
