30 and calcification distribution were the most reliable signs for the diagnosis of breast cancer. The shape and size of calcification also were helpful to the differential diagnosis of benign and malignant breast lesions.

Objective To investigate iron deposition level in patients with ischemic cerebrovascular disease and its correlation with cerebral small vessel disease (CSVD) imaging markers.Methods A total of 74 patients with first-ever transient ischemic attack (TIA) (median age:69 years old;30 males,44 females) and 77 patients with positive ischemic stroke history (median age:72 years old;43 males,34 females) were studied retrospectively.On phase image of susceptibility weighted imaging (SWI),regions of interest (ROIs) were manually drawn at the bilateral head of the caudate nucleus (CN),lenticular nucleus (LN),thalamus (TH),frontal white matter (FWM),and occipital white matter (OWM).The correlation between iron deposition level and the clinical and imaging variables was also investigated.Results Iron deposition level at LN was significantly higher in patients with previous stroke history (P ＜ 0.05).It was linearly correlated with the presence and number of cerebral microbleed (CMB) but not with white matter hyperintensity (WMH) and lacunar infarct.Conclusions Ischemia may cause iron deposition elevation at basal ganglia,and LN may be more susceptible to ischemia-induced alteration.CMB may be an independent risk factor for higher iron deposition.

OBJECTIVE: To determine diagnostic value of liver CT for acute necrotizing pancreatitis. METHODS: A total of 130 patients with the acute necrotizing pancreatitis underwent abdominal helical contrast CT scanning, whose pancreatitis was graded and the live CT values were measured. RESULTS: Altogether 111 patients had decreased liver CT value.Twenty-seven patients with decreased liver CT value were in Grade I, 54 in Grade II, 21 in Grade III, and 9 in Grade IV. There was a negative correlation between CT grades of the liver and CT value of acute necrotizing pancreatitis (r = -0.279, P = 0.008). CONCLUSION The CT value of liver density has diagnostic value in acute necrotizing pancreatitis.
