| 1 | Diagnostic efficacy of gadoxetic acid-enhanced MRI for hepatocellular carcinoma and dysplastic nodule显示文摘AIM:To evaluate the relationship between the signal intensity of hepatobiliary phase images on gadoxetic acid-enhanced magnetic resonance imaging(MRI)and histological grade.METHODS:Fifty-nine patients with 82 hepatocellular lesions were evaluated retrospectively.Hepatobiliary phase images on gadoxetic acid-enhanced MRI were classified into 3 groups:low,iso or high.Angiographyassisted computed tomography(CT)findings were also classified into 3 groups:CT during arterial portography,and CT hepatic arteriography:A:iso,iso or low;B:slightly low,iso or low;;and C:low,high.We correlated angiography-assisted CT,hepatobiliary phase findings during gadoxetic acid-enhanced MRI and histological grades.Furthermore,correlations between MRI findings and histological grade for each hemodynamic pattern were performed.Correlations among radiologicaland pathological findings were statistically evaluated using the chi-square test and Fisher's exact test.RESULTS:There was a significant correlation between histological grade and hemodynamic pattern(P<0.05).There was a significant correlation between histological grade and signal intensity in the hepatobiliary phase(P<0.05)in group A lesions.There was no significant correlation between histological grade and signal intensity in the hepatobiliary phase in group B or C lesions(P>0.05).CONCLUSION:Signal intensity in the hepatobiliary phase correlated with histological grade in the lesions that maintained portal blood flow,but did not correlate in lesions that showed decreased or defective portal blood flow. | Kazuhiro Saito Ryota Nishio Toru Saguchi Soichi Akata Koichi Tokuuye Fuminori Moriyasu Katsutoshi Sugimoto Junichi Taira Toshitaka Nagao | 2011 | World Journal of Gastroenterology2011，17，30： | 12 |

| 19 | Transcatheter arterial embolization for traumatic injury to the pharyngeal branch of the ascending pharyngeal artery:Two case reports显示文摘BACKGROUND The ascending pharyngeal artery(APhA)comprises the pharyngeal trunk(PT)and neuromeningeal trunk.The PT feeds the nasopharynx and adjacent tissue,which potentially connects with the sphenopalatine artery(SPA),branched from the internal maxillary artery(IMA).Due to its location deep inside the body,the PT is rarely injured by trauma.Here,we present two cases that underwent transcatheter arterial embolization(TAE)of the PT of the APhA due to trauma and iatrogenic procedure.CASE SUMMARY Case 1 is a 49-year-old Japanese woman who underwent transoral endoscopy under sedation for a medical check-up.The nasal airway was inserted as glossoptosis occurred during sedation.Bleeding from the nasopharynx was observed during the endoscopic procedure.As the bleeding continued,the patient was referred to our hospital for further treatment.Contrast-enhanced computed tomography(CT)demonstrated extravasation in the nasopharynx originating from the right Rosenmuller fossa.TAE was performed and the extravasation disappeared after embolization.Case 2 is a 28-year-old Japanese woman who fell from the sixth floor of a building and was transported to our hospital.Contrastenhanced CT demonstrated a complex facial fracture accompanying extravasation in the left pterygopalatine fossa to the nasopharynx.Angiography demonstrated an irregular third portion of the IMA.As angiography after TAE of the IMA demonstrated extravasation from the PT of the APhA,additional TAE to the artery was performed.The bleeding stopped after the procedure.CONCLUSION Radiologists should be aware that the PT of the APhA can be a bleeding source,which has a potential connection with the SPA. | Daisuke Yunaiyama Yuki Takara Takehiro Kobayashi Mika Muraki Taro Tanaka Mitsuru Okubo Toru Saguchi Motoki Nakai Kazuhiro Saito Kiyoaki Tsukahara Yuri Ishii Hiroshi Homma | 2022 | World Journal of Clinical Cases2022，10，32： | 0 |
