PURPOSE: The purpose of this study was to prospectively evaluate the detectability and usefulness of automated whole breast ultrasound (AWUS) and to compare it with handheld breast ultrasound (HHUS) in cases with suspicious microcalcifications identified by mammography. METHODS: Forty-two patients with 43 suspicious microcalcifications (25 malignant and 18 benign) detected by mammography underwent AWUS, HHUS, and histol-ogic examination. With knowledge of the mammographic findings, HHUS was performed to assess the visibility of the microcalcifications and the presence of associated masses or ductal changes. Two radiologists reviewed the AWUS images in consensus using the same methods employed for HHUS. Detectability of AWUS was compared with that of HHUS and was correlated with histologic and mammographic findings. RESULTS: Of the 43 lesions, 32 (74.4%) were detectable by AWUS and 31 (72.1%) by HHUS. No significant differences in sensitivity were found between the two methods (p=0.998). AWUS detected 96% (24/25) of malignant microcalcifications and 44.4% (8/18) of benign microcalcifications. AWUS was more successful in the detection of malignant vs. benign lesions (96.0% vs. 44.4%, p=0.002), lesions >10 mm vs. ≤10 mm in size (86.7% [26/30] vs. 46.2% [6/13], p=0.009), lesions with a fine pleomorphic or linear shape vs. a round or amorphous or coarse heterogeneous shape (94.7% [18/19] vs. 58.3% [14/24], p=0.021), and lesions associated with a mass or architectural distortion vs. without obvious changes on mammography (100% [19/19] vs. 54.2% [13/24], p=0.022). CONCLUSION: Detectability of AWUS was comparable to that of HHUS in cases where suspicious microcalcifications were identified on mammography. Therefore, AWUS might be helpful in the performance of ultrasound-guided percutaneous procedures for highly suspicious microcalcifications.

PURPOSE: To evaluate the magnetic resonance imaging (MRI) and clinicopathological features of triple negative breast cancer, and compare them with those of non-triple negative breast cancer. MATERIALS AND METHODS: This study included 231 pathologically confirmed breast cancers from January 2007 to May 2008. We retrospectively reviewed the MRI findings according to the Breast Imaging Reporting and Data System (BI-RADS) lexicon: mass or non-mass type, mass shape, mass margin, non-mass distribution, and enhancement pattern. Histologic type, histologic grade, and the results for epidermal growth factor receptor, p53, and Ki 67 were reviewed. RESULTS: Of 231 patients, 43(18.6%) were triple negative breast cancer. Forty triple negative breast cancers (93.0%) were mass-type lesion on MRI. A round or oval or lobular shape (p=0.006) and rim enhancement (p=0.004) were significantly more in triple negative breast cancer than non-triple negative breast cancer. In contrast, irregular shape (p=0.006) and spiculated margins (p=0.032) were significantly more in non-triple negative breast cancer. Old age (p=0.019), high histologic grade (p<0.0001), EGFR positivity (p<0.0001), p53 overexpression (p=0.038), and Ki 67 expression (<0.0001) were significantly associated with the triple negative breast cancer. CONCLUSION: MRI finding may be helpful for differentiation between triple negative and non-triple negative breast cancer.

PURPOSE: The aim of this study was to evaluate the usefulness of MRI performed after excisional biopsy to diagnose residual cancer and additional lesions. MATERIALS AND METHODS: A total of 16 patients who had breast cancer diagnosed by excisional biopsy underwent preoperative breast MRI between March 2005 and August 2007 were included. MRI findings were considered positive for residual cancer if focal, thick, or irregular rim enhancement or adjacent enhancing lesion was identified around the postoperative biopsy cavity. And additional lesions separated from biopsy cavity including multifocal, multicentric, or contralateral lesion were evaluated. We evaluated the diagnostic accuracy of MRI, comparing MRI with histopathologic finding, and the impact of MRI on surgical planning. RESULTS: The sensitivity and specificity of MRI for detecting residual disease considering rim enhancement were 85.7%(6/7) and 55.6%(5/9). Additional lesions including multifocal, multicentric, or contralateral lesion were found in 6 patients. In 7 patients, results of MRI findings changed surgical treatment planning. CONCLUSION: The pattern of rim enhancement on MRI after excisional biopsy is not differential point to evaluate remnant lesion. But MRI has an important role to help the detection of multifocal or multicentric, or contralateral breast malignancies, resulting in beneficial change in surgical treatment planning.

PURPOSE: Split-thickness skin grafts (STSG), as a treatment of full thickness burn have played a significant role in re-surfacing to date. The major disadvantage of traditional STSG is related to donor site morbidity, including scar formation and cosmetic changes. SureDerm(TM) is acellular human dermis, which is intended for the repair or replacement of damaged soft tissue. Then, we present our experience of using SureDerm(TM) as a tool for the skin graft of full thickness burns. METHODS: We reviewed the medical records of 20 patients treated in our burn center who received SureDerm(TM) graft with thin STSG in full thickness burns since November 2006 to October 2008. RESULTS: SureDerm(TM) was used with thin STSG (range 0.006~0.008 inches) concurrently. Thickness of SureDerm(TM) was 0.2~0.4 mm and the type of SureDerm(TM) was meshed. The average size of SureDerm(TM) used in the burn patients was 329.6 cm2 (32~1,384). All burn areas grafted SureDerm(TM) were full thickness burns and the locations were upper and lower extremities including joints (8 and 6 cases), trunk (3 cases), ankle (2 cases), and axilla (1 case). Each SureDerm(TM) grafted area had more than 95% take-rate. No complications were observed except 1 case of partially infected STSG. The mean follow up period was 8.7 months (1~17), and the assessment of scars, which had more than six months follow up periods was performed by Modified Vancouver Scar Scale and the results were good. CONCLUSION: SureDerm(TM) can be used as a dermal substitute for the treatment of full thickness burns and the result seems to be good cosmetically and functionally while it solves donor site morbidity followed by autograft.

PURPOSE: This study evaluated the accuracy of three-dimensional gadolinium-enhanced MR angiography (Gd-MRA) in the preoperative evaluation of living renal transplant donors (LRTDs) for visualizing the renal vascular anatomy, with an emphasis on identifying the number of renal arteries and veins and the presence of small branch anomalies. MATERIALS AND METHODS: Between April 1999 and October 2003, a total of 42 LRTDs were evaluated with conventional renal angiography (CRA) or three-dimensional Gd-MRA. The three-dimensional Gd-MRA was performed in 20 cases and CRA in 22. All candidates then underwent a donor nephrectomy. The intraoperative findings of the renal vessels were compared between the CRA and three-dimensional Gd-MRA, and the complications and side effects also examined. RESULTS: The overall accuracies for predicting the numbers and abnormalities of renal arteries and veins by comparing the intraoperative findings were 85 and 95% for the three-dimensional Gd-MRA, and 91 and 98% for the CRA. The three-dimensional Gd-MRA missed 3 accessory renal arteries, while the CRA missed 1, as well as 1 renal artery bifurcation. There were three complications; one contrast anaphylaxis and two hematomas at the puncture site, in the 22 CRA cases, but there were no significant complications in the three-dimensional Gd-MRA. CONCLUSIONS: Three-dimensional Gd-MRA appears to be as accurate as CRA for visualizing the renal vascular anatomy in the preoperative assessment of potential LRTDs. Three-dimensional Gd-MRA is a noninvasive and noncontrast technique, which would be a good alternative to CRA for assessing potential LRTDs.

PURPOSE: The purpose of this study was to establish optimal imaging acquisition conditions for the GE Advance(TM) PET imaging system by performing the acceptance tests designed by National Electrical Manufacturers Association (NEMA) protocol and General Electric Medical Systems (GEMS) test procedures. MATERIALS AND METHODS: Performance tests were carried out with 18FDG radioactivity source and phantoms by using a standard acquisition mode. Transaxial resolution and scatter fraction tests were performed with a line source and axial resolution with a point source, respectively. A cylindrical phantom made of polymethylmethacrylate (PMMA) was used to measure sensitivity, count rate losses and randoms, uniformity correction, and attenuation inserts were added to measure remaining tests. The test results were acquired in a diagnostic acquisition mode and analyzed mainly on high sensitivity mode. RESULTS: Transaxial resolution and axial resolution were measured as average of 4.65 mm and 3.98 mm at 0 cm, and 6.02 mm and 6.71 mm at 20 cm on high sensitivity mode, respectively. Average scatter fraction was 9.87%, and sensitivity was 225.8 kcps/micronCi/cc of trues. Activity at 50% deadtime was 4.6 Ci/cc, and the error of count rate correction at that activity was from 1.49% to 3.83%. Average nonuniformity for total slice was 8.37%. The accuracy of scatter correction was -0.95%. The accuracies of attenuation correction were 5.68% for air, 0.04% for water and -6.51% for polytetrafluoroethylene (PTFE). CONCLUSION: The results satisfied most acceptance criteria, indicating that the GE AdvanceTM PET system can be optimally used for clinical applications.

Cystic lymphangioma of the broad ligament is very rare benign cystic lesion. They rarely present in adult life. We present the case of a 37-year-old female with a history of chronic recurrent left lower abdominal dull pain over a period of several months. Clinical presentation of these tumors varies greatly from an asymptomatic mass to serious complications. The therapy of choice is a complete excision, unless vital structures were involved. Once excised, the prognosis is excellent. Our patient had complete excision of her lesion with a good outcome.
