“…Accordingly, preoperative staging breast MRI is recommended in various clinical scenarios by senological guidelines and is routinely performed in many institutions before surgery (10). Furthermore, there is also a rising number of trials indicating that preoperative staging breast MRI might be used not only as a diagnostic but also as a prognostic tool (11)(12)(13)(14)(15). This is driven by the hypothesis, that contrast enhanced imaging of breast cancer with breast MRI is able to assess tumor vasculature and neoangiogenesis induced by the neoplasm (16)(17)(18).…”

This study demonstrates the significant relationship between semi-quantitative enhancement analysis in breast MRI and disease-related death of breast cancer patients. As results were extracted from a routine staging examination, MRI noninvasively provides not only diagnostic information but also outcome data at one step. Future studies should address the impact of these findings on patient management and therapeutic approach.

“…Anders sieht die Situation bei den Online-Zugriffen aus: 4 Artikel wurden von den RöFo-Lesern überdurchschnittlich oft abgerufen: Im Artikel zur Ganzkörper-MRT in der präoperativen Diagnostik des Mammakarzinoms [51] wird eine Alternative zu den nuklearmedizinischen Stagingmethoden aufgezeigt. Im Artikel von Dietzel et al aus 2011 [52] wird das Potenzial der MagnetResonanz-Mammografie zur Abschätzung des Differenzierungsgrads invasiver Mammakarzinome evaluiert und es stellt sich die Frage, ob die MRT dies hinreichend genau leisten kann oder ob doch die Biopsie notwendig ist. Ein weiterer online häufig frequentierter Artikel beschreibt den Einfluss des Hormonstatus auf Hintergrundanreicherungen und die diagnostische Genauigkeit der MR-Mammografie mit erheblicher Relevanz u. a. für die Terminierung der MRT bei prämenopausalen Frauen [53].…”

“…With these criteria, breast MRI has a sensitivity of about 85 % to 99 % in detecting malignant breast lesions, as has been shown in several studies [1, 2, 16 -24]. Recently, the implementation of MRI exams in regular screening settings has been discussed as well [19,25,26]. If MRI of the breast is to be used under screening conditions, the shortening of protocols would be preferable.…”

Purpose?The aim was to evaluate a minimum echo time (minTE) protocol for breast magnetic resonance imaging (MRI) in patients with breast lesions compared to a standard TE (nTE) time protocol. Methods?Breasts of 144 women were examined with a 1.5 Tesla MRI scanner. Additionally to the standard gradient-echo sequence with nTE (4.8?ms), a variant with minimum TE (1.2?ms) was used in an interleaved fashion which leads to a better temporal resolution and should reduce the scan time by approximately 50?%. Lesion sizes were measured and the signal-to-noise ratio (SNR) as well as the contrast-to-noise ratio (CNR) were calculated. Subjective confidence was evaluated using a 3-point scale before looking at the nTE sequences (1?=?very sure that I can identify a lesion and classify it, 2?=?quite sure that I can identify a lesion and classify it, 3?=?definitely want to see nTE for final assessment) and the subjective image quality of all examinations was evaluated using a four-grade scale (1?=?sharp, 2?=?slight blur, 3?=?moderate blur and 4?=?severe blur/not evaluable) for lesion and skin sharpness. Lesion morphology and contrast enhancement were also evaluated. Results?With minTE sequences, no lesion was rated with ?definitely want to see nTE sequences for final assessment?. The difference of the longitudinal and transverse diameter did not differ significantly (p?>?0.05). With minTE, lesions and skin were rated to be significantly more blurry (p?

Potential of MR Mammography to Predict Tumor Grading of Invasive Breast Cancer

Abstract: MR mammography was able to non-invasively assess tumor grading in a standard protocol. Since tumor grading is a surrogate for overall survival, these results provide further evidence to the clinical application of MR mammography as a noninvasive prognostic tool.
