Department of Radiology

Background: Breast cancer is the most common cancer in females, both in developed and developing countries. Pakistan has the highest breast cancer incidence rate in Asia. Guidelines recommend screening for detecting breast cancer with mammography and ultrasonography (US). Shear-wave elastography (SWE) is a newer technique that can aid additional characterization of breast lesions.
Objective: The aim of this study was to determine the diagnostic accuracy of breast ultrasound elastography in differentiating benign from malignant breast lesions using histology diagnosis as the gold standard.
Materials and methods: The study was conducted at the Abbasi Shaheed Hospital and Jinnah Post Graduate Medical …

Assessment Of Magnetic Resonance Imaging Safety: Allied Health Professional Clinical Competence, Tiffany Houser

Electronic Theses and Dissertations

Magnetic resonance imaging is a major advancement in the diagnostic imaging field. Most patients can tolerate an MRI however, there are some who are unable to complete a lengthy scan while lying completely still without sedatives or anesthesia. Non-MRI healthcare providers are trained to use equipment that is “unsafe” in the MRI suite due to the strong magnetic field. Staff who are not fully knowledgeable and trained in MRI safety measures can endanger staff and patients.

The purpose of this study was to determine the knowledge level of non-MRI healthcare providers regarding safety risks associated with MRI and to determine …

Process Improvement For Follow-Up Radiology Report Recommendations Of Lung Nodules., Philip S. Lim, Doron Schneider, Jonathan Sternlieb, Michel Taupin, Nicholas Sich, Joan Diaz, Eileen Jameson, Bryan Frambes, Sharon Taylor

Abington Jefferson Health Papers

In the modern healthcare system, there are still wide gaps of communication of imaging results to physician and patient stakeholders and tracking of whether follow-up has occurred. Patients are also unaware of the significance of findings in radiology reports. With the increase in use of cross-sectional imaging such as CT, patients are not only being diagnosed with primary urgent findings but also with incidental findings such as lung nodules; however, they are not being told of their imaging findings nor what actions to take to mitigate their risks. In addition, patients at high risk for developing lung cancer often obtain …

Primary Malignant Melanoma Of Brainstem Medulla Mimicking As Cavernoma, Adnan Naeem, Fatima Mubarak

Department of Radiology

Aim of this case report is to present a rare case of primary malignant melanoma of brain stem at the region of medulla oblongata mimicking as cavernoma. 40-year-old male presented with vertigo, headache, dizziness for 1 month. MRI showed pear shaped T1 hyperintense lesion at medulla oblongata and predominantly hypointense on T2 with focal area of hemorrhage. Lesion showed diffuse enhancement on postcontrast images. On plain CT lesion was Hyperdense. It was initially reported as Cavernoma. Surgical excision of lesion was done with per-op findings of solid, dark maroon colored lesion with hemorrhage. Histopathology showed neoplastic lesion with abundant melanin …

Radiation Safety Practices Of Dental Hygienists In The United States, Kimberly Lintag, Ann M. Bruhn, Susan Lynn Tolle, Norou Diawara

Dental Hygiene Faculty Publications

Purpose: The As Low As Reasonably Achievable (ALARA) principle was developed to promote awareness and minimization of radiation exposure and is supported by radiation control and professional organizations. The purpose of this study was to determine licensed dental hygienists' current radiation safety practices.

Methods: Data were collected with a 22 item, online survey administered to a convenience sample of 1,500 dental hygienists in the United States. Questions focused on respondents' use of the American Dental Association (ADA) radiographic examination selection guidelines, their individual dental practice policies, and hand-held portable x-ray device use and training. Cross tabulations were obtained using logistic …
