Purpose: The purpose of this study was to evaluate the usefulness of dynamic spiral CT, including multidimensional reformation, in the detection and localization of islet cell tumors of the pancreas. Material and Methods: Seven patients with histopathologically proven functioning islet cell tumors of the pancreas were studied with 2-phase contrast-enhanced spiral CT. Scanning of the arterial phase and late phase was started 30 s and 180 s, respectively, after injection of 100 ml of contrast medium at a rate of 3 ml/s. Results: Axial images in the arterial phase depicted the lesions in 5 patients, but in the late phase in only one patient. Multiplanar reformatted images of the arterial phase depicted the lesions in all 7 patients. Maximal intensity projection images demonstrated all lesions with information of their relationship to the vascular structure. Conclusion: Dynamic spiral CT with scanning during the arterial phase and retrospective multidimensional reformation is useful for preoperative detection and localization of small islet cell tumors of the pancreas.

Detection And Localization

Background: Sentinel lymph node (SLN) location and biopsy was designed to minimize side effects of axillary dissection with equivalent outcomes. Aim: To evaluate the feasibility of periareolar injection of contrast agent SonoVueTM followed by ultrasound (US) for identification and localization of SLN in breast cancer patients with clinically negative node. Methods: From July 2017 through January 2018, 130 women were enrolled in the study. SonoVueTM was injected periareolarly and followed by US to detect enhanced sentinel lymphatic channels (SLCs) and SLNs 1 minute later after massage. The patients were randomly divided into two groups to locate the first enhanced SLN: 1) US-guided marker placing; 2) US-guided nano-carbon (N) injection into SLN. Compare the number of SLNs detect by CEUS with blue dye (B) or N mapping, and the coincidence rate of the first SLN located by CEUS with those traced by the B and N. Lymph nodes that were dark, blue, with marker or clinically positive were considered sentinel nodes and to be biopsied. Results: 121 of 130 patients with breast cancer patients injected with ultrasound contrast agents had detected a total of 254 enhanced SLNs (range 1-5, 2.1 ± 1.05) compared with total of 342 SLNs (range 1-5, 2.83 ± 1.10) mapping with B or N. 42 of 45 first SLNs located with marker matched with first SLNs stained with N (42/45, 93.33%); 70 of 76 first SLNs using N injecting directly guided by CEUS matched with first SLNs stained with B (70/76, 92.1%). In another 9 cases without enhanced SLN, 4 of them didn't stained with N or B, and 5 were stained. The sensitivity of SLNs detection by CEUS was 96.03% (121/126), and the accuracy of locating the first SLN was 92.56% (112/121). Conclusion: CEUS has good accuracy in the detection and localization of SLNs in patients with breast cancer.
