Iodine-125 (I-125) labelled radioactive seeds were the first published wireless pre-operative image-guided breast localization technique. Radioseeds offer benefit to radiologists as a relatively intuitive procedure with precise mammographic or sonographic-guided localization and improved patient experience. Localization and surgical dates can be uncoupled, which facilitates efficient scheduling for radiologists and surgeons. Surgeons can better tailor their surgery with intra-operative localization using a special probe to detect the emitted gamma energy...

When cancer is detected in a screening mammogram, on occasion retrospective review of prior screening (pre-index) mammograms indicates a likely presence of cancer. These missed cancers during pre-index screens constitute a delay in detection and diagnosis. This study was undertaken to quantify the missed cancer rate by auditing pre-index screens to improve the quality of mammography screening practice. From a cohort of 135 screen-detected cancers, 120 pre-index screening mammograms could be retrieved and served as the study sample...

There are several steps involved in a breast cancer diagnosis, starting from the initial abnormal screening mammogram. Each step from the additional imaging to a biopsy provokes anxiety. Timely attention to these appointments will not only help allay anxiety but also provide better care. While breast facilities routinely audit their performance, currently timeliness is not one of the audit parameters. The role of timeliness as a robust quality tool is gaining attention. In this study, we review the timeline of care at our facility over a 1-year period (October 2021- September 2022) and compare them with those reported by National Quality Measures for Breast Centers (NQMBC)...

JOURNAL ARTICLE
Joao V Horvat
High-risk lesions or lesions of uncertain malignant potential are frequent findings on image-guided needle biopsy of the breast and comprise a number of distinct entities. These lesions are known for having risk of underlying malignancy and are usually associated with an increased lifetime risk for breast cancer. Surgical excision was traditionally recommended for all high-risk lesions but recent studies have demonstrated that vacuum-assisted excision or surveillance may be adequate for some lesions. While management of high-risk lesion varies among institutions, this chapter describes the management recommendations based on recent literature of the most frequent types of lesions...

REVIEW

Mammographic breast density is widely accepted as an independent risk factor for the development of breast cancer. In addition, because dense breast tissue may mask breast malignancies, breast density is inversely related to the sensitivity of screening mammography. Given the risks associated with breast density, as well as ongoing efforts to stratify individual risk and personalize breast cancer screening and prevention, numerous studies have sought to better understand the factors that impact breast density, and to develop and implement reproducible, quantitative methods to assess mammographic density...

This topical review is focused on the clinical breast x-ray imaging applications of the rapidly evolving field of artificial intelligence (AI). The range of AI applications is broad. AI can be used for breast cancer risk estimation that could allow for tailoring the screening interval and the protocol that are woman-specific and for triaging the screening exams. It also can serve as a tool to aid in the detection and diagnosis for improved sensitivity and specificity and as a tool to reduce radiologists' reading time...

Cybersecurity in healthcare is a very real threat with the potential to severely disrupt patient care, place extra burden on an already strained system, and result in significant financial losses for a hospital or healthcare network. In October 2020, on the backdrop of the ongoing COVID-19 pandemic, our institution experienced one of the most significant cyberattacks on a healthcare system to date, lasting for nearly 40 days. By sharing our experience in radiology, and specifically in breast imaging, including the downtime procedures we relied upon and the lessons that we learned emerging from this cyberattack, we hope to help future victims of a healthcare cyberattack successfully weather such an experience...

Breast-conserving surgery or lumpectomy requires localization of the lesion prior to surgery, which is traditionally accomplished by imaging-guided wire localization. Over the last decade, alternatives to wire localization have emerged. This work reviews the literature on one such wireless technology, SaviScout radar (SSR) system, and shares our experience with using this technology for presurgical tumor localization. The SSR surgical guidance system is non-radioactive. The radiologist implants a reflector device in the breast under mammography or ultrasound guidance at any time prior to surgery...

Fibropolycystic liver disease is a continuum of disorders that result from insults to the ductal plate at different stages of development and are often associated with each other. Caroli's syndrome, polycystic liver disease, biliary hamartomas, and congenital hepatic fibrosis are included in this complex spectrum that also shows frequent association with renal anomalies, such as polycystic kidney disease and medullary sponge kidney. Choledochal cysts are a controversial point in this topic since they have long been considered part of this spectrum due to morphological similarities, but studies have shown different pathogenesis...

Although the liver may present a range of congenital anomalies, often involving shape irregularities or the number of lobules, less common variations include the presence of accessory liver lobes (ALL), consisting of a supernumerary lobe of normal hepatic parenchyma in continuity with the liver. This paper reviews the embryology, frequency, anatomy, and types of ALL. Furthermore, we describe computed tomography and magnetic resonance imaging findings in a range of such cases, including those simulating disease or presenting with complications...

A wide range of conditions involving the cecum may be found in patients undergoing imaging work-up for conditions as various as right lower pain, diarrhea, fever, and weight loss. The cecum may be the only area of involvement by a particular disease. However, it may also be affected by a more diffuse process of the gastrointestinal tract or even as part of systemic diseases. Imaging provides an excellent evaluation of the cecal region and its surrounding planes, with an impactful clinical application in multiple scenarios...

MRI plays an integral role in the initial local staging of rectal cancer and assessment of treatment response, with the goal of treatment to minimize local recurrence. Standard treatment of rectal cancer includes surgical excision with the addition of neoadjuvant chemoradiation therapy for locally advanced disease. MRI is ideally suited for both surgical planning and risk stratification, allowing for accurate evaluation of tumor location and characteristics, T and N staging, and other MRI-specific features...

The value of computed tomographic colonography (CTC) as a sensitive diagnostic investigation for colorectal cancer is well established. However, there is lack of consensus in the best way to achieve expertise in interpreting these studies. In this review we discuss the value of CTC training, accreditation and performance monitoring; the qualities of good CTC interpretation training, and specific training cases with associated learning points.

The abducens, or the sixth cranial nerve, is purely motor and runs a long course from the brainstem to the lateral rectus. Travels with the inferior petrosal sinus through the Dorello's canal before entering the cavernous sinus. Based on the location of an abnormality, other neurologic structures may be involved with the disturbs related to this nerve. This article aims to review the abducens nerve anatomy and demonstrates the imaging aspect of the diseases that most commonly affect it.
