ABSTRACT
Objective To investigate the diagnostic value of high-resolution CT (HRCT) with systemic lupus erythematosus (SLE) lung lesions. MethodRetrospective analysis of clinical diagnosis of SLE have pulmonary infiltration in patients with CT and 28 cases of lung HRCT performance was Conducted. Result28 patients showed different degrees of pulmonary fibrosis to mainly peripheral distribution, Iobular septal thickening and ground-glass density in the performance of its common. ConclusionsHRCT check can help determine the extent of pulmonary infiltration SLE, and preliminary estimates of prognosis. Lobular septal thickening and ground-glass density are the early performance of SLE ,while honeycomb cysts change is the peature in advanceal stage.
ABSTRACT
Objective To explore MRI findings of intervertebral suppurative spondylitis. Methods MRI findings of intervertebral suppurative spondylitis in 12 cases proved by surgery and 6 cases defined by clinical features were retrospectively analyzed. The MRI protocol included un-enhanced conventional scan in 18 cases and contrast-enhanced scan in 11 cases. Results Of the 18 cases, single focus was found in 16 cases, and multiple loci were seen in 2 cases. MRI findings included (1) Disappearance sign of nuclear crevice in 17 cases, accumulated fluid sign of intervertebral disc in 15 cases, intervertebral disc perforation in 4 cases, and intervertebral space narrowing in 7 cases. (2) Bone destruction under end plate and marrow oedema were shown in 18 cases, 17 cases had end plate destruction, 16 cases had covered sign of end plate.(3) Paraspinal soft tissue swelling was shown in 18 cases, in which thick wall microabscess was formed in 4 cases. (4) Vertebral canal was involved in 12 cases, vertebral canal abscess was formed in 5 cases.(5) Lump enhancement was demonstrated in 4 cases, nodular enhancement in 2, and ring-like enhancement in 2, respectively. No enhancement was seen in 3 cases. Dural sac linear enhancement was shown in 6 cases, and patchy enhancement in the anterior dural sac was shown in 10 cases. Conclusion Intervertebral suppurative spondytitis had characteristic MRI findings, and the key to correct diagnosis was to combine MRI finding with clinical characteristics.
