ABSTRACT
Objective To investigate X-ray manifestations of mammary hamartoma and its pathologic basis.Methods 19 cases were proved by surgery and pathology,X-ray and pathologic manifestations were analyzed.All cases were examined with full digital mammography.Results X-ray manifestations of mammary hamartomas were divided into three types,including fat type were in 5 cases;dense type were in 4 cases and mixed type were in 10 cases.The lumps were surrounded by a true capsule in pathology,they were made up of different amount of rambling mammary ducts,lobules,adipose and fibrous tissue.Conclusion X-ray manifestations of mammary hamartoma are varied,depending on the proportion of the adipose tissue,gland and fibrous tissue.Mixed density lump is the characteristic sign of this disease.
ABSTRACT
Objective To improve the understanding of giant hypertrophy of the gastric mucosa.Methods Giant hypertrophy of the gastric mucosa in 6 cases proved by operation or gastroscopy biopsy pathological examination were reviewed.Barium meal examination was performed in all cases,CT in 3 cases.B-type ultrasound in 2 cases.Results It was ease to be misdiagnosed giant hypertrophy of the gastric mucosa on the basis of the conventional imaging appearances.Laboratory data and gastroscopy biospsy played an important role in diagnosis and differential diagnosis.Conclusion Giant hypertrophy of the gastric mucosa is uneasily to correct diagnosed,comprehensive evaluation is necessary for it.
ABSTRACT
Objecteve To study the relation between the enhanced CT image parameters and metastasis, type of peripheral lung cancer. Methods The enhanced CT image parameters of 138 peripheral lung cancers confirmed by pathology were analyed retrospectively. Both plane scan and contrast-enhanced CT were performed in all the patients, and boundary CT value of each lung cancer was measured. Results Contrast-enhanced CT showed that peripheral lung cancer had big and bent peripheral vessels, and the peripheral density of tumor mass was correlated with its metastasis. The frequency of adenocarcinoma metastasis was higher than that of squamous carcinoma. Conclusion Contrast-enhanced CT was helpful for predicting the latent possibility of peripheral lung cancer metastasis.
ABSTRACT
The double-window technique was applied in 30 patients with thoracic diseases in CT examination. The pictures of lung window, mediastinum window and double-window were read respectively and the diagnostic accuracy were compared. The principle, advantage and limitation of double-window technique were discussed.
