This heterogeneity has been correlated with the level of tumor response to neoadjuvant chemotherapy. A significant number of studies using magnetic resonance imaging have looked into the quantification of intra tumor heterogeneity in breast cancer. Nevertheless, a limited number of these studies have specifi-cally looked at evaluating breast cancer heterogeneity as a biomarker of response to treatment. Methods: In this paper, several heterogeneity quantification methods, which have studied breast cancer response to treatment through MR images, will be presented. Important methodological and technological techniques using experimental design, such as histogram analysis, texture analysis and parametric response mapping (PRM), will be explored. Results: Data acquisition, the number of patients, the number of treatment cycles, and other analysis will be discussed for each presented research case. Furthermore, some proposed methods will be evaluated on our institution MRI dataset, collected between 2013 and 2016. Conclusion: This paper can be used as a guideline for investigators working on breast cancer het-erogeneity as a biomarker of response to treatment.","PeriodicalId":13333,"journal":{"name":"Imaging in Medicine","volume":"5 1","pages":"109-119"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90866934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been recommended that CTPA may be performed only in patients with positive D-dimer assays and clinical suspicion of PTE (pulmonary thromboembolism), to curb unnecessary imaging and health care costs. We wanted to reassess the validity of this recommendation by looking into the D-dimer results in patients with positive PTE on CTPA. Methods: All patient records with positive PTE diagnosis on CTPA and having relevant laboratory data during one calendar year (January 01 to December 31, 2009) were selected. Serum D-dimer values of >500 ng/ml was considered abnormal. The D-dimer results among the patients who had the test performed were tabulated based on age and sex along with those without D-dimer assay in the same groups and correlated with their percentage distribution. Results: Out of a total of 98 positive PTE cases on CTPA, only 26 patients (26.5%) had a serum D-dimer assay done prior to CTPA. Of these, 20 (76.9%) had elevated values and 6 cases (23.1%) had a negative test. Negative D-dimer results varied with patient age, being highest in the 21-40 years age group. Conclusion: Overall, there seems to be more preferred use of CTPA and underutilization of serum D-dimer assay in clinical practice for suspected PTE. Secondly, negative D-dimer assay should not be used to triage patients with a high clinical index of suspicion for PTE.","PeriodicalId":13333,"journal":{"name":"Imaging in Medicine","volume":"21 1","pages":"81-84"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82702493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study’s aim was to evaluate breast blood supply using MRI and to compare it between oncological and non-oncological subjects. The risk factors for NAC necrosis in nipple sparing mastectomy were analyzed. Methods: Breast MRI exams in one month at a single institution were evaluated. The considered inclusion criteria focused on patients with: ductal carcinoma in situ, invasive carcinoma (IC) or high-risk screening (HRS) without previous breast surgery. Subtraction reconstructions from dynamic acquisitions obtained at 60 s post-contrast administration were used. Results: 166 breasts were evaluated (12 pre op DCIS; 42 HRS; 112 pre op IC) - 71% of the NAC’s had a dominant blood supply. Tumors were localized in the upper outer quadrant (UOQ) in 46% of cases. In the NAC vascularization analysis, there was a tendency for a higher number of vessels vascularizing the NAC in the IC group (p=0.056) and there was a difference in the quadrant analysis mainly at the UOQ that had a dominant blood supply in 18% of the IC group and only 2% in the HRS (p=0.048). 16 patients performed NSM, three had NAC necrosis. The number of vessels supplying the NAC was the only factor with correlation with this outcome (p=0.01). There was not a single NAC with a dominant blood vessel from the lower outer quadrant (LOQ). Conclusion: Using MRI to pre-operatively evaluate breast blood supply is feasible without adding extra MRI time or contrast. 71% had dominant supply to the NAC, so every effort should be made to preserve it. The LOQ appears to be an optimal site for skin incisions. There is an asymmetry between cancer and HRS breasts mainly at the NAC’s level with neovascularization of that area. Patients with a single vessel supplying the NAC are at improved risk for necrosis.","PeriodicalId":13333,"journal":{"name":"Imaging in Medicine","volume":"19 1","pages":"215-222"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75004359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
