Tuesday's Press Conferences
Watch for stories in the national media generated by RSNA press conferences:
Even Mild Coronary Artery Disease Puts
Diabetic Patients at Risk
Using the CONFIRM Registry, developed to examine the prognostic value of cardiac CT angiography (CCTA) for predicting adverse cardiac events related to coronary artery disease, researchers studied data on 1,823 diabetic patients who underwent CCTA to detect and determine the extent of coronary artery disease. Major adverse cardiovascular event (MACE) data was available on 973 patients and 30.3 percent experienced a MACE during the follow-up period. The study indicated that both obstructive and mild, or non-obstructive, coronary artery disease were related to patient deaths and MACE and that the relative risk for death or MACE for a patient with mild coronary artery disease was comparable to that of patients with single vessel obstructive disease.
DBT Improves Cancer Detection in Dense Breasts
Digital breast tomosynthesis (DBT) has the potential to significantly increase the cancer detection rate in mammography screening of women with dense breasts. Researchers compared cancer detection using full-field digital mammography (FFDM) versus FFDM plus DBT in 25,547 women between the ages of 50 and 69. Of 257 cancers detected, 82 percent were detected with FFDM plus DBT, a significant improvement over the 163 detected with FFDM alone. FFDM plus DBT pinpointed 63 percent of the 132 cancer cases in women with dense breasts, compared to only 59 percent for FFDM alone. The findings showed an overall relative increase in the cancer detection rate with DBT of about 30 percent, and an increase in detection of invasive cancers of about 40 percent.
Risk-based Screening Misses Breast Cancers in Women in Their Forties
This study found that using a risk-based approach to screening mammography could potentially miss more than 75 percent of breast cancers in women in their 40s. The retrospective study included 136 women between the ages of 40 and 49 with breast cancer identified by screening mammography between 1997 and 2012. Of the 136 breast cancer cases identified, 50 percent were diagnosed as invasive and 50 percent were diagnosed as ductal carcinoma in situ (DCIS). A very strong family history was absent in 90 percent of patients, and extremely dense breast tissue was absent in 86 percent. Seventy-eight percent of patients had neither strong family history nor extremely dense breasts, including 79 percent of the cases of invasive disease.
Patients Take Control of Their Medical Exam Records
Researchers set out to evaluate patient and provider satisfaction with RSNA Image Share, an Internet-based interoperable image exchange system that gives patients ownership of their imaging exams and control over access to their imaging records. Patients undergoing any radiologic exams in four academic centers were eligible to establish online patient health record (PHR) accounts using the network. Between July 2012 and August 2013 the study enrolled 2,562 participants, who were provided a brief survey to assess patient and physician experience with the exchange of images. Ninety-six percent of survey respondents valued having direct access to their medical images. In addition, a greater percentage of Internet users reported being able to access their images without difficulty, compared to CD users.
Today's Press Conferences
RSNA invites members of the medical news media to attend its annual meeting each year so that, through stories in print, broadcast and Internet media, the public gains a greater understanding of radiology and its role in their healthcare.
Three press conferences will be held today:
- Interventional Radiology Procedure Preserves Uterus in Patients with Placenta Accreta
- Common Knee Surgery May Lead to Arthritis and Cartilage Loss
- Many Chest X-rays in Children Are Unnecessary
