MRI of High-Risk Breast Lesions
Some benign pathologic entities of the breast, when diagnosed at image-guided core needle biopsies, have the potential to be upgraded to invasive carcinoma or ductal carcinoma in situ (DCIS) upon…
MRI Features of Invasive Disease
Breast magnetic resonance imaging (MRI) has become an important part of the work-up of patients with newly diagnosed breast cancers. Although no large studies have proved a survival advantage, and…
MRI Features of Ductal Carcinoma in Situ
Ductal carcinoma in situ (DCIS) now makes up 20% to 30% of newly diagnosed breast cancers, an increase in detection that is largely attributed to the advent of screening mammography….
Optimizing the Breast MRI Protocol
Optimizing the breast magnetic resonance imaging (MRI) protocol requires many decisions to be made about image acquisition techniques, types of pulse sequences, and sequence parameters used to control image quality…
Computer-Aided Detection for Breast MRI
Optimal breast magnetic resonance imaging (MRI) interpretation depends on the image reader’s ability to both detect and accurately characterize contrast enhanced breast lesions. Detecting areas of enhancement involves the tedious…
Screening for Breast Cancer with MRI
Breast cancer remains the second leading cause of cancer death in women. Mammography is the single large-scale method currently employed in screening for breast cancer in asymptomatic women. Although the…
Setting Up and Optimizing a Breast MRI Practice
Breast magnetic resonance imaging (MRI) was introduced into the breast imaging community in the 1990s. A considerable number of research studies were conducted, with findings revealing promising results Breast MRI…
The Fetal Skeletal System
The Fetal Skeletal System INTRODUCTION Ultrasound in the first trimester provides a distinct advantage over ultrasound in the second and third trimester of pregnancy for the evaluation of the fetal…
The Fetal Central Nervous System
The Fetal Central Nervous System INTRODUCTION The evaluation of the fetal central nervous system (CNS) is an important aspect of ultrasound in the first trimester given that several major malformations,…
The Fetal Gastrointestinal System
The Fetal Gastrointestinal System INTRODUCTION Ultrasound examination of the fetal abdomen in the first trimester includes the assessment of abdominal organs from the diaphragm superiorly to the genitalia inferiorly. This…
