“…The high spatial resolution of the ultrafast images used the current study, certainly contributed to the high sensitivity of the current study. For example, Oldrini et al, 8 using an earlier version ultrafast sequence, with both poorer spatial resolution and temporal resolution than the current study, reported missing six cancers because of poor spatial resolution.…”

“…I n The past few years, many centers have implemented the ultrafast dynamic contrast enhancement (DCE) sequence in their magnetic resonance imaging (MRI) protocol for breasts imaging the flow of contrast agent from the heart to breast tissue. [1][2][3][4][5][6][7][8][9] The principle of discrimination between benign and malignant lesions in the breasts based on the time of arrival (ToA) of the contrast agent from the aorta to the lesion was first published in 1994. Boetes et al 10,11 found that contrast agent usually arrived at malignancies before 11.5 seconds, while the ToA to benign lesions was usually longer.…”

“…A recent article reported that including the ultrafast sequence improved the specificity of an FDP. An improved specificity yields a lower recall rate in screening, avoiding unnecessary biopsies, patient stress, and potentially less treatment.…”

Background Each ultrafast dynamic contrast‐enhanced (DCE) MRI sequence for breast cancer generates thousands of images in a 4D stack that need to be reviewed by a radiologist. Purpose To assess whether color intensity projections (CIP) effectively summarizes—using only the time of arrival (ToA) and amount of signal enhancement (AoE) of the contrast agent—the thousands of ultrafast images. Study Type Retrospective cohort clinical trial. Subjects The study included 89 patients who had been scanned with an MRI beast protocol, of which 26 had breast cancer and 63 did not. Field Strength/Sequence The 115‐second ultrafast DCE sequence at 3T acquired 19 consecutive frames every 4.26 seconds with 152 slices per frame, yielding a 4D stack with 2888 2D images for each of water and fat. Assessment For each slice of the water 4D stack a single CIP image was generated that encoded the ToA in the hue (red, orange, yellow, green, cyan, blue) and AoE in the brightness. Each of three experienced radiologists assigned a Breast Imaging and Reporting Data System (BI‐RADS) score for each patient, first using only the CIP images, and subsequently using both CIP and the full 4D stack. Statistical Tests The one‐sided Fisher's exact test was used to determine statistical significance of both the sensitivity and specificity between the CIP alone and the CIP plus 4D stack. Results All malignancies were detected using only CIP by at least one of the radiologists. The CIP and CIP+4D sensitivities for reader 1 were 96% and 96% (P = 0.57), specificities were 59% and 65% (P = 0.29). For reader 2, the values were 96% and 100% (P = 0.51) with 62% and 71% (P = 0.17). For reader 3 the values were 92% and 96% (P = 0.50) with 51% and 62% (P = 0.07). Data Conclusion With a 95% sensitivity, CIP provides an effective summary of ultrafast DCE images of breast cancer. Level of Evidence: 3 Technical Efficacy: Stage 2 J. Magn. Reson.

“…Oldrini et al evaluated time‐resolved imaging of contrast kinetics (TRICKS) acquisitions compared with an abbreviated as well as a full diagnostic protocol . The authors achieved an improved specificity when TRICKS acquisitions were added to the abbreviated protocol, outperforming the full protocol.…”

“…In efforts to overcome these limitations and facilitate increased access to screening breast MRI, Kuhl et al initially introduced an abbreviated breast MRI protocol for screening that substantially shortened examination and reading times; at the same time, this protocol maintained a diagnostic accuracy equivalent to a full diagnostic protocol . Thereafter, several other studies have investigated different abbreviated and high‐temporal resolution MRI protocols for breast cancer diagnosis and screening, with similar results . This review will provide an overview of the current published literature on abbreviated breast MRI and its potential clinical applications and challenges.…”
