MR imaging of the lymphatic system: distribution and contrast enhancement of gadodiamide after intradermal injection.
We examined 24 lower extremities in 12 patients with lymphedema to evaluate the distribution and enhancement of gadodiamide after intradermal injection for MR imaging of lymphatic pathways in lymphedematous patients. The lymphedema was bilateral in 8, unilateral in 4, and 3 patients suffered from lymphedema in the genital region. 9 mL of gadodiamide and 1 mL of mepivacainhydrochloride 1% were d...
متن کاملPersistent MR contrast enhancement of calcified neurocysticercosis lesions.
PURPOSE We sought to determine whether cysticercosis lesions in the brain continue to enhance after nodular involution and complete calcification, and to investigate the clinical significance of this finding with respect to seizure recurrence after cysticidal treatment. METHODS Serial contrast-enhanced MR images were obtained in all patients with neurocysticercosis seen at our hospital over a...
متن کاملInterval between injection of contrast material and positive contrast cheliography affects accurate diagnosis of diaphragmatic hernia
The aim of this study was to evaluate the clinical, surgical and diagnostic imaging findings in 11 cats and 3 dogs with suspected acute and chronic traumatic diaphragmatic hernia, and to compare the results of positive contrast cheliography (peritoneography) taken immediately and 5 min after the injection of contrast material. Thoracic and abdominal radiography, ultrasonography, and positive co...
متن کاملContrast-enhanced spiral CT of the head and neck: comparison of contrast material injection rates.
BACKGROUND AND PURPOSE Contrast-enhanced spiral CT studies of the head and neck are performed frequently using contrast material volumes of approximately 30 g iodine and a scan delay of 30-45 seconds. Because little is known about the effects of contrast material injection rates on tissue enhancement, this was prospectively investigated in our study. METHODS Ninety-seven patients underwent sp...
متن کاملFocal Hepatic Lesions: Contrast-Enhancement Patterns at Pulse-Inversion Harmonic US using a Microbubble Contrast Agent
OBJECTIVE To analyze the contrast-enhancement patterns obtained at pulse-inversion harmonic imaging (PIHI) of focal hepatic lesions, and to thus determine tumor vascularity and the acoustic emission effect. MATERIALS AND METHODS We reviewed pulse-inversion images in 90 consecutive patients with focal hepatic lesions, namely hepatocellular carcinoma (HCC) (n=43), metastases (n=30), and hemangi...
