Abstract:  The purpose of this study was to compare the ability of magnetic resonance imaging (MRI) and mammography to determine the presence and extent of ductal carcinoma in situ (DCIS). Retrospective review of medical records of women who underwent MRI and mammographic examination during a 23‐month period revealed 39 sites of pure DCIS in 33 breasts of 32 women. No invasive or microinvasive tumor was found. Women ranged in age from 34 to 79 years (mean age 53 years). In these 33 breasts, both MRI and mammography were done before surgery. Reports and images of mammography and MRI were reviewed to determine if each study was positive for the presence of single or multiple sites of DCIS and the imaging patterns associated with these sites. Of 33 breasts involved, DCIS was discovered by MRI alone in 21 (64%), by both MRI and mammography in 8 (24%), and by mammography alone in 1 (3%); in 3 breasts (9%), DCIS was found at mastectomy without findings on mammography or MRI. MRI had significantly higher sensitivity than mammography for DCIS detection (29/33 = 88% versus 9/33 = 27%, p < 0.00001). Multiple sites of disease were present in five breasts; these were better demonstrated with MRI in three, mammography in one, and equally by both in one. The predominant enhancement pattern of DCIS on MRI was linear/ductal in 18 of 29 breasts (62%); mammography found calcifications associated with DCIS in 8 of 9 (89%). The nuclear grade of DCIS found with MRI and mammography was similar; size of lesions was larger on MRI; breast density did not impact results. In this study, MRI was significantly more sensitive than mammography in DCIS detection. In women with known or suspected DCIS, MRI may have an important role to play in assessing the extent of disease in the breast.

The purpose of the current study was to determine the frequency of ‘probably benign’ interpretations at breast magnetic resonance (MR) imaging screening of high‐risk women and the frequency of subsequent malignancy in these women.

OBJECTIVE To evaluate the ability of an abbreviated breast magnetic resonance imaging (MRI) protocol, consisting of a precontrast T1 weighted (T1W) image and single early post-contrast T1W image, to detect breast carcinoma. MATERIALS AND METHODS A HIPAA compliant Institutional Review Board approved review of 100 consecutive breast MRI examinations in patients with biopsy proven unicentric breast carcinoma. 79% were invasive carcinomas and 21% were ductal carcinoma in situ. Four experienced breast radiologists, blinded to carcinoma location, history and prior examinations, assessed the abbreviated protocol evaluating only the first post-contrast T1W image, post-processed subtracted first post-contrast and subtraction maximum intensity projection images. Detection and localization of tumor were compared to the standard full diagnostic examination consisting of 13 pre-contrast, post-contrast and post-processed sequences. RESULTS All 100 cancers were visualized on initial reading of the abbreviated protocol by at least one reader. The mean sensitivity for each sequence was 96% for the first post-contrast sequence, 96% for the first post-contrast subtraction sequence and 93% for the subtraction MIP sequence. Within each sequence, there was no significant difference between the sensitivities among the 4 readers (p=0.471, p=0.656, p=0.139). Mean interpretation time was 44s (range 11-167s). The abbreviated imaging protocol could be performed in approximately 10-15 min, compared to 30-40 min for the standard protocol. CONCLUSION An abbreviated breast MRI protocol allows detection of breast carcinoma. One pre and post-contrast T1W sequence may be adequate for detecting breast carcinoma. These results support the possibility of refining breast MRI screening protocols.

Histologic Heterogeneity of Masses at Percutaneous Breast Biopsy

The purpose of this study was to determine whether different histologic findings are obtained from different areas of breast masses seen on mammography when targeted on stereotactic breast biopsy. Twenty‐one masses (mean size, 1.8 cm; range, 0.7–5.5 cm) underwent stereotactic biopsy using a 14‐gauge directional vacuum‐assisted biopsy probe (Mammotome, Biopsys/Ethicon Endo‐Surgery, Cincinnati, OH). The central and peripheral areas of the mass were targeted and biopsied separately, and histologic findings from the targeted center and periphery were compared. Six of 21 masses (29%) were heterogeneous, yielding different histologic results from the targeted center and periphery. In 4 heterogeneous masses, which constituted 4 of 21 masses (19%) in this study, surgical biopsy was recommended on the basis of findings obtained from only the center (n = 2) or the periphery (n = 2). Stereotactic biopsy findings in these 4 masses were atypia in 3 and radial scar in 1; none of these 4 masses had carcinoma at surgery. In all 4 masses that proved to be malignant, the diagnosis of carcinoma was made in specimens obtained from both the targeted center and the periphery of the mass. Breast masses can be heterogeneous, yielding different histologic findings from different areas of the mass. Our data suggest that sampling part but not all of a mass may miss certain histologic components of the mass, but should not result in a failure to diagnose carcinoma.

Wallstent Migration Following Deployment in Right and Left Bile Ducts

Andrea F. Abramson; Daniel J. Javit; Harold A. Mitty; John S. Train; Sol J. Dan

The Wallstent biliary endoprosthesis has recently been approved for treatment of malignant bile duct obstruction. Although minor changes in position have occurred, migration of these stents has been uncommon. The authors report a case in which migration occurred when stents were simultaneously deployed in the right and left bile ducts. Several mechanisms for this complication are postulated.

Assessment of response to therapy of primary breast cancer by mammography and physical examination

D. David Dershaw; Susan Drossman; Laura Liberman; Andrea F. Abramson

Background. Accurate assessment of response to treatment is necessary to treat appropriately primary breast cancers that are not surgically removed. This retrospective study was undertaken to compare the effectiveness of physical examination (PE) and mammography to assess response of primary breast cancer to medical therapy in women who were ineligible for initial surgical treatment.

Update on interventional treatment of urinary obstruction.

Andrea F. Abramson; Harold A. Mitty

During the last 20 years percutaneous nephrostomy has evolved as one of the basic procedures in the management of obstructive uropathy. This procedure is now widely available, it is relatively safe, and it offers rapid treatment of urinary obstruction regardless of underlying cause. Percutaneous nephrostomy is also the first step in a variety of antegrade ureteral procedures, including stent placement and ureteral dilation.

Dilated periportal lymphatics mimicking an anastomotic bile leak after liver transplantation

Andrew M. Rabin; Andrea F. Abramson; Cosme Manzarbeitia; Harold A. Mitty; Charles M. Miller; John S. Train; Sol J. Dan

Transhepatic cholangiography is commonly performed during postoperative evaluation of liver transplant patients. The authors describe a potential pitfall in the interpretation of these studies and illustrate that dilated interrupted lymphatics of the donor liver can mimic a periductal leak of contrast material.
