Objective
To evaluate the correlation between duration of dysphagia and magnetic resonance image (MRI) findings in patients with stroke. Method: Ninety seven patients, who were evaluated by video fluoroscopic swallowing studies (VFSS), were recruited for 28 months. They were divided into two groups (transient group (n=52), prolonged group (n=45)) by removing time of NG tube from onset of stroke. Their MRI findings (lesion location and lesion size) were interpreted by one experienced radiologist retrospectively. Results: The duration of dysphagia had statistically significant correlation with lesion size but there was no statistically significant correlation between lesion location and duration of dysphagia in patients with stroke. Compared with transient group (51.5±53.8 cm³), a larger lesion was found in prolonged group (95.5±107.7 cm³). Conclusion: Lesion size, not lesion location, can be a more important factor to predict early removal of NG tube in patients with stroke. More careful interventions about dysphagia are needed in patients with larger stroke lesion. (J Korean Acad Rehab Med 2010; 34: 498-502)

Objective
To localize lesions which correlate with depression after stroke. Method: This study was performed in 98 stroke patients who admitted at two hospitals in Daegu in 2006. Lesions on magnetic resonance imaging were reviewed by same neuroradiologist and depression was diagnosed by same phychiatrist using DSM-III-R and ICD-10 criteria. We tried to find the correlation between the lesion location and depression.Results: Depression was not related to age, sex, dominant hemisphere, underlying disease (HTN, DM, heart disease), and many lesions of interest of brain. Lesions in prefrontal area, limbic lobe, cingulate gyrus, post white matter and frontal lobe correlated significantly with depression.Conclusion: We found that there was a strong correlation between post stroke depression and the pathologic lesion which is frontal-subcortical circuit except basal ganglion and thalamus.
