[The significance of ultrasound and mammography in the diagnosis of fat necrosis after fat transplantation in breasts].

Objective: To investigate the significance and images characters of ultrasound and mammography in the diagnosis of fat necrosis after fat transplantation in breasts(FTB).

Methods: From June 2005 to June 2012, 13 cases with 96 fat necrosis lumps after FTB, were retrospectively reviewed. The pre-operative images of ultrasound and mammography, as well as the post-operative histologic results were collected.

Autologous fat grafting to the breast for cosmetic enhancement: experience in 66 patients with long-term follow up.

Background: Autologous fat grafting to the breast for cosmetic enhancement remains controversial because the efficacy and fate of fat grafting to the breast are primarily unknown. In this report, we present our retrospective study in 66 patients who underwent autologous fat grafting to the breast for various cosmetic reasons and who were followed with sonography, mammography, or magnetic resonance imaging (MRI).

Methods: Sixty-six patients who desired cosmetic enhancement of the breast for various reasons underwent autologous fat transplantation between August 2000 and March 2005 in our institution.

[CT analysis of 69 patients with nasopharyngeal carcinoma invading the Cranio-maxillofacial structures].

Purpose: To analyze the characteristics of involvement of surrounding tissues in nasopharyngeal carcinoma(NPC).

Methods: CT images of 69 cases with preradiotherapeutic nasopharyngeal carcinoma were analyzed to calculate the rates of anterior spread(including pterygoid plates,pterygopalatine fossa, maxillary sinus, ethmoidal sinus, nasal cavity), lateral spread(including palatal muscle, parapharyngeal space, carotid sheath and infratemporal fossa), medial spread(including pharyngeal cavity, the contralateral side of the nasopharynx), posterior spread(including prevertebral muscle, cervical vertebra and clivus), superior spread(including sphenoidal sinus,foramen lacerum, foramen ovale, greater wing of sphenoid bone, petrous apex and intracranial region), inferior spread(including oropharynx, parapharyngeal space, soft palate, hard palate) respectively.

Results: 18 cases of in this series had anterior spread(26.
