Calibration process for improving Crystal Identification rate in the LabPET™ phoswich detectors

AbstractThis study examines the production and perception of corrective focus in South Kyungsang Korean, using phone number strings. It shows that focus prosody varies greatly by tonal pattern (HHL, HLL, LHT, LHL) within phrases. Prosodic focus in High-initial phrases was clearly produced and accurately recognized, compared to that in Low-initial phrases. Additionally, the identification rate of HLL was higher than that of HHL, mainly because the focused initial H of the HHL contrasted with the second H within phrases, in terms of pitch. The results confirm that the encoding of prosodic focus is not uniform within a language; rather, focus prosody within a language can vary depending on the tonal pattern of an utterance.

Aims: The clinical significance of nonvisualized sentinel lymph nodes (non-vSLNs) is unknown. The authors sought to determine the incidence of non-vSLNs on lymphoscintigraphy, the identification rate during surgery, factors associated with non-vSLNs and related axillary management. Patients & methods: A total of 30,508 consecutive SLN procedures performed at a single institution from 2000 to 2017 were retrospectively studied. Associations between clinicopathological factors and the identification of SLNs during surgery were assessed. Results: Non-vSLN occurred in 525 of the procedures (1.7%). In 73.3%, at least one SLN was identified intraoperatively. Nodal involvement was only significantly associated with SLN nonidentification (p < 0.001). Conclusion: Patients with non-vSLN had an increased risk for SLN metastasis. The detection rate during surgery was consistent, reducing the amount of unnecessary axillary dissection.
