The objective of the present study was the evaluation of MRI of the breast in the follow-up of patients who had undergone
autogenous tissue breast reconstruction using either a latissimus-dorsi muscle flap or a transverse rectus abdominis myocutaneous
(TRAM) flap as correlated with patients' clinical, conventional mammographic and sonographic findings. Included in the study
were 41 patients. The MRI consisted of T2-weighted turbo spin-echo (TSE) sequences and dynamic measurements pre- and postcontrast
using T1-weighted gradient-echo (GE) sequence. The following factors were evaluated: recognition of the flap; evidence of
edema; skin thickening; and focally increased contrast medium uptake. Contrast medium dynamics were documented in instances
of increased focal uptake. Flaps could be distinguished from surrounding residual breast tissue in all cases. Edema and skin
thickening in the residual mammary tissue and flap implant were observed in 72.7% of patients undergoing radiation, but in
only 15.8% of those not undergoing radiotherapy. The MRI excluded disease recurrence in 4 patients with suspicious mammographic
and/or sonographic findings. One instance of multifocal disease recurrence identified at MRI evaded detection with all other
imaging techniques used. The MRI returned false-positive findings in three cases. Because of their configuration and contrast
medium uptake dynamics and their location immediately adjacent to the contact zone between the flap implant and residual mammary
tissue, these findings were impossible to differentiate from a recurrent carcinoma. The MRI of the breast is generally suitable
for follow-up examination of autogenous tissue reconstructions. Problems may be encountered in the evaluation of the contact
zone between local adipose tissue and the flap leading to false-positive results.

Objective
This study aimed at determination of the MRI predictors of triple negative breast cancer (TNBC) in comparison to other breast cancer subtypes.Materials and methods
The study retrospectively enrolled 185 female patients with 206 pathologically confirmed invasive breast cancers with different subtypes by immunohistochemistry. Histopathological analysis as well as MRI features of TNBC was compared to those of other breast cancer subtypes. MRI features included the tumor size, shape, margin, internal enhancement, intratumoral signal intensity on T2-WI, detectability by DW-MRI and ADC values.Results
TNBCs showed higher histological grades (p < 0.0001) and younger patient age group (p = 0.006) compared to other tumor subtypes. At MRI, TNBCs were of larger size (p < 0.0001), round shape (p < 0.0001), smooth margin (p < 0.0001), with rim enhancement (p < 0.0001) and higher incidence of T2-WI tumoral hyperintensity (p = 0.0002) and intratumoral necrosis (p < 0.0001). No significant difference in tumor detectability was found by DW-MRI, however, TNBCs had higher ADC values (p < 0.0001).Conclusion
In our study, TNBC patients were of younger age with higher grade malignancy. TNBC MRI predictors were unifocal rim enhancing mass with round shape, smooth margin, higher signal intensity on T2-WI, in addition to relatively larger sizes of tumors associated with high incidence of intratumoral necrosis and higher ADC values. 相似文献10.
目的 应用锥形束CT分析改良头颈肩热塑体膜和乳腺托架在乳腺癌改良根治术后调强放疗中的摆位精度差异。方法 回顾性分析天津医科大学肿瘤医院2015年8月至2018年12月68例接受调强放疗(IMRT)的乳腺癌改良根治术后患者资料。根据体位固定方式的不同,将患者分为改良头颈肩热塑体膜组(体膜组,42例)和乳腺托架组(托架组,26例)。在患者的第1、6、11、16、21次治疗摆位后行锥形束CT(CBCT)扫描,获得两组患者在左右(RL)、腹背(AP)、头脚(SI)方向的摆位误差,同时记录放疗摆位的时间。比较两组的摆位误差、分布比例、摆位时间,计算出各自的MPTV外放值,并分析多种因素对体膜组患者摆位误差的影响。结果 42例体膜组扫描210次,26例托架组扫描130次。体膜组和托架组在RL、AP、SI方向的摆位误差分别为(2.12±2.01)和(2.38±1.92)mm、(3.29±2.46)和(3.88±2.76)mm、(3.47±2.29)和(4.11±3.15)mm,其中两组在AP和SI方向的摆位误差比较,差异均有统计学意义(t=-2.05、-2.16,P<0.05);SI方向体膜组摆位误差≤ 3 mm的次数占总扫描次数的比例较高,优于托架组差异有统计学意义(χ2=4.97,P<0.05);当AP和SI方向体膜组摆位误差>5 mm的次数占总扫描次数的比例较低,优于托架组差异有统计学意义(χ2=5.21、9.29,P<0.05)。体膜组的摆位时间较短,优于托架组差异有统计学意义(t=-2.16,P<0.05)。RL、AP、SI方向体膜组计算的MPTV值均小于托架组。改良头颈肩热塑体膜体位固定方式对高龄(≥ 60岁)、体质量指数(BMI)≥ 24 kg/m2和对放疗过程相对不熟悉(治疗时间≤ 2周)的患者会造成AP和(或)SI方向的摆位误差偏大。其中,SI方向<60岁的患者摆位误差较小,优于高龄患者(≥ 60岁)差异有统计学意义(t=-2.43,P<0.05);AP和SI方向BMI<24 kg/m2的患者摆位误差较小,优于BMI ≥ 24 kg/m2的患者,差异有统计学意义(t=-2.21、-2.04,P<0.05);AP方向治疗时间>2周的患者摆位误差较小,优于对放疗过程相对不熟悉的患者(治疗时间≤ 2周)差异有统计学意义(t=2.23,P<0.05)。结论 在乳腺癌改良根治术后IMRT放疗时应用改良头颈肩热塑体膜可以降低腹背和头脚方向的摆位误差,同时缩短摆位时间。对于≥ 60岁、BMI ≥ 24 kg/m2和对放疗过程相对不熟悉(治疗时间≤ 2周)的患者,要关注腹背和头脚方向的摆位,以保证放疗的效果。 相似文献

Purpose
To quantify variations within and between observers ascribable to manual region of interest (ROI) placement in patients with breast cancer undergoing dynamic MRI.Materials and Methods
Expert and nonexpert observers independently outlined tumor ROIs on 30 dynamic T1‐weighted (T1W) MRI scans on five occasions over two months. Lesion size (number of pixels) and kinetic parameter estimates, including the transfer constant (Ktrans), were calculated for each ROI placement. Inter‐ and intraobserver variability was assessed with respect to the interval between drawings, lesion morphology, and observer experience.Results
For the nonexpert, the variability reduced with decreasing time intervals between ROI drawings (the coefficient of variance (wCV) values at two months, two weeks, one day, and same‐day time intervals were respectively 11.6%, 10.7%, 4.8%, and 2.6% for lesion size, and 8.9%, 9.7%, 6.7%, and 3.2% for Ktrans). For the expert observer, the variability was smaller overall and more constant, but improved for same‐day ROI placements (region size wCV: 7.5%, 6.2%, 7.1%, and 3.7%; Ktrans wCV: 5.4%, 5.3%, 5.6%, and 4.5%).Conclusion
Significant observer variability in manual ROI placement occurs in dynamic MRI of breast cancer. For serial patient studies, ROI placements should be outlined at the same sitting to minimize observer error. J. Magn. Reson. Imaging 2006. © 2006 Wiley‐Liss, Inc.13.
ObjectivesAnalysing the influence of additional carcinoma in situ (CIS) and background parenchymal enhancement (BPE) in preoperative MRI on repeated surgeries in patients with invasive lobular carcinoma (ILC) of the breast.MethodsRetrospective analysis of 106 patients (mean age 58.6 ± 9.9 years) with 108 ILC. Preoperative tumour size as assessed by MRI, mammography and sonography was recorded and compared to histopathology. In contrast-enhanced MRI, the degree of BPE was categorised by two readers. The influence of additionally detected CIS and BPE on the rate of repeated surgeries was analysed.ResultsAdditional CIS was present in 45.4% of the cases (49/108). The degree of BPE was minimal or mild in 80% of the cases and moderate or marked in 20% of the cases. In 17 cases (15.7%) at least one repeated surgery was performed. In n = 15 of these cases, repeated surgery was performed after BCT (n = 9 re-excisions, n = 6 conversions to mastectomy), in n = 2 cases after initial mastectomy. The initial surgical procedure (p = 0.008) and additional CIS (p = 0.046) significantly influenced the rate of repeated surgeries, while tumour size, patient age and BPE did not (p = ns).ConclusionsAdditional CIS was associated with a higher rate of repeated surgeries, whereas BPE had no influence. 相似文献

Purpose
To determine the utility of MRI for assessing axillary lymph node status in patients with breast cancer.Materials and Methods
A consecutive series of patients who underwent breast MR before surgical management of breast cancer with axillary sampling between 2005 and 2007 were identified. MRs were evaluated for the number of nodes, contrast kinetics, nodal area, and number of nodes with no fatty hilum. Data were analyzed in the context of final breast pathology, sentinel lymph node status, and axillary nodal status. Correlations were analyzed using Kendall's τ‐b test. Reported P values are one‐sided.Results
Fifty‐six females (median = 58 years) were studied. Sentinel lymph nodes (SLN) were positive in 15/56 patients (27%). All SLN + patients (n = 15) had completion axillary dissection. Extent of nodal disease was 1 (n = 3), 2 (n = 4), >2 (n = 8). Presence of any axillary lymph node with no fatty hilum and the number of nodes with no fatty hilum on MR significantly correlated with pathologic node positivity (P = 0.04); while kinetics, node number, and node size did not correlate.Conclusion
Breast MR may be useful in the assessment of axillary nodes in patients with breast cancer. J. Magn. Reson. Imaging 2009. © 2009 Wiley‐Liss, Inc. 相似文献16.
