In this chapter we focus on image segmentation techniques for some very special images — textile images. They are generated from the color halftoning technique in textile and printing production lines. In contrast with natural color images, textile images have some very distinctive features: (1) generally there are a few dominant colors in a textile image, whereas there may exist hundreds of si...

Recent evidence suggests an association between vasospastic angina and Brugada syndrome. Here we present two cases of coronary artery disease who presented with ECG abnormalities which might have been provoked or enhanced by ischemia of the conus branch of the right coronary artery. The 12-lead ECGs demonstrated normal sinus rhythm in these two cases. Interestingly, a saddle back or coved type ...

Bitemporal visual field defects are usually associated with lesions of the optic chiasm. The field loss may be caused by pressure, primary neoplasia, arachnoiditis, or demyelinating disease. While the findings of a bitemporal defect should always direct attention to these possibilities, a careful inspection of the optic disc may reveal an ocular cause for the field loss. The purpose of this com...

BACKGROUND Peripapillary intrachoroidal cavitation was described as the presence of an asymptomatic, well-circumscribed, yellow-orange, peripapillary lesion at the inferior border of the myopic conus in eyes with high myopia. CASE PRESENTATION A 66-year-old myopic Chinese man was enrolled and his multi-color imaging examination showed a well-circumscribed, caesious, peripapillary lesion coale...

Absent F wave in the stage of spinal shock has been described in cases of traumatic spinal cord injury. The role of F wave in predicting prognosis after conus medullaris infarct has not been described. We describe herein a middle aged-man with a conus medullaris infarct. Both tibial and peroneal F waves were absent on day 4. The left tibial F wave reappeared in the following study on day 18. Al...

intradural tumors (WHO grade I) that characteristically occur in the conus medullaris/filum terminale region. They are slow growing tumors with a good prognosis and long-term survival.1 We report a rare case of double MPE occurring at both extremities of the filum terminale. In the light of the present case and an extensive review of the literature, we summarize the imaging characteristics and ...

Results Seven of the 41 patients had positive reactions to textile related allergens on the screening or textile series and five were thought to be work-related. Four patients who were patch test positive with the textile series were also positive to relevant allergens on the screening series. Two patients with work-related textile dermatitis were patch test positive to the textile series but n...

MR examinations of the spine were reviewed in 25 patients with a clinical diagnosis of tethered spinal cord. In 21 patients (84%), the level of the tip of the conus was below the mid L2 vertebral body. The causes of the tethering were spinal lipomas (72%), tight filum terminale syndrome (12%), diastematomyelia (8%), and myelomeningocele (8%). These entities were readily identified in all instan...

The coexistence of spinal teratoma of the conus medullaris and arteriovenous malformation (AVM) is exceptional, which has not been reported previously in the literature. The precise mechanism of the coexistence of these conditions is not known, however, the dysembryonic origin of spinal cord teratoma and AVM seems to play a part in this process. A 34-year-old male patient was admitted with lowe...

Abstract. Solar-induced chlorophyll fluorescence (SIF) has previously been shown to strongly correlate with gross primary productivity (GPP); however this relationship not yet quantified for the recently launched TROPOspheric Monitoring Instrument (TROPOMI). Here we use a Gaussian mixture model develop parsimonious between SIF from TROPOMI and GPP flux towers across conterminous United States (...
