概述

进行腹部CT检查的目的是为了了解腹腔脏器有没有感染性疾病,如:炎症、结核、脓肿等;有没有占位,如良、恶性肿瘤,转移性肿瘤等;有没有畸形、结石、梗阻、穿孔、积液等。 正常CT表现CT图像为腹部某一横断图像,须根据各脏器的解剖部位进行扫描。不同脏器的正常CT表现如下:肝脏:CT可显示肝脏轮廓、大小、密度和内部结构。正常肝脏密度均匀,CT值为40-70H,比脾脏高。不同层面上,所显示的肝脏各叶、段的大小、形状有所不同。如肝门以层,可显示“H”形低密度带状影。右纵裂为胆囊窝,左纵裂为肝镰状

A 51-year-old man with a history of hypertension, hypercholesterolemia, and nephrolithiasis presented to the emergency department with left flank and left upper quadrant abdominal pain.He stated that“I think I have a kidney stone blocking my kidney”but denied nausea, vomiting, fever, dysuria, hematuria, or weight loss. He had no history of chronic abdominal pain. Past surgical history was noteworthy for emergency exploratory laparotomy and splenectomy for blunt trauma 14 years prior. Physical examination revealed a comfortable-appearing patient in no acute distress. His temperature was 36.8°C;pulse, 77/min; and blood pressure, 125/86 mmHg. Abdominal palpation elicited only mild epigastric tenderness without masses or rebound. There was no costovertebral angle tenderness.Laboratory data revealed normal levels of serum urea nitrogen and creatinine and normal liver function. A complete blood cell count showed leukocytosis (15300/μL with 54% neutrophils, 38% lymphocytes, 8% monocytes); hemoglobin level, 15.5g/dL; and hematocrit, 45.2%. Urinalysis revealed no red or white blood cells and was negative for leukocyte esterase and nitrate.
