Patient Access of Their Radiology Reports Before and After Implementation of 21st Century Cures Act Information-Blocking Provisions at a Large Multicampus Health System.

BACKGROUND. To implement provisions of the 21st Century Cures Act that address information blocking, federal regulations mandated that health systems provide patients with immediate access to elements of their electronic health information, including imaging results. OBJECTIVE. The purpose of this study was to compare patient access of radiology reports before and after implementation of the information-blocking provisions of the 21st Century Cures Act. METHODS. This retrospective study included patients who underwent outpatient imaging examinations from January 1, 2021, through December 31, 2022, at three campuses within a large health system. The system implemented policies to comply with the Cures Act information-blocking provisions on January 1, 2022. Imaging results were released in patient portals after a 36-hour embargo period before implementation versus being released immediately after report finalization after implementation. Data regarding patient report access in the portal and report acknowledgment by the ordering provider in the EMR were extracted and compared between periods. RESULTS. The study included reports for 1,188,692 examinations in 388,921 patients (mean age, 58.5 ± 16.6 [SD] years; 209,589 women, 179,290 men, eight nonbinary individuals, and 34 individuals for whom sex information was missing). A total of 77.5% of reports were accessed by the patient before implementation versus 80.4% after implementation. The median time from report finalization to report release in the patient portal was 36.0 hours before implementation versus 0.4 hours after implementation. The median time from report release to first patient access of the report in the portal was 8.7 hours before implementation versus 3.0 hours after implementation. The median time from report finalization to first patient access was 45.0 hours before implementation versus 5.5 hours after implementation. Before implementation, a total of 18.5% of reports were first accessed by the patient before being accessed by the ordering provider versus 44.0% after implementation. After implementation, the median time from report release to first patient access was 1.8 hours for patients with age younger than 60 years old versus 4.3 hours for patients 60 years old or older. CONCLUSION. After implementation of institutional policies to comply with 21st Century Cures Act information-blocking provisions, the length of time until patients accessed imaging results decreased, and the proportion of patients who accessed their reports before the ordering provider increased. CLINICAL IMPACT. Radiologists should consider mechanisms to ensure timely and appropriate communication of important findings to ordering providers.

FDG PET/CT and thyroid biopsy leads to neurosarcoidosis diagnosis.

We present a unique case of neurosarcoidosis diagnosed based on thyroid biopsy and FDG PET (Fluorodeoxyglucose positron emission tomography) imaging. A patient presented for a second opinion after being placed in hospice for rapidly progressing dementia, presumed to be due to Creutzfeldt Jakob disease despite negative workup and was unable to perform activities of daily life or communicate with his wife. The patient underwent a workup including whole-body FDG PET, which showed hypermetabolic lymph nodes as well as a hypermetabolic nodule in the thyroid. Biopsy of the lymph nodes was nondiagnostic, but the thyroid biopsy tissue yielded a diagnosis of sarcoid. After ruling out other causes and reviewing the tissue pathology, the patient was diagnosed with systemic sarcoidosis with neurological involvement and started on infliximab with rapid improvement.

Severe Mpox Proctitis Complicated by Bowel Obstruction.

Mpox is a rare infection caused by the zoonotic orthopoxvirus. We present the case of a 44-year-old man with HIV and a history of kidney transplant who presented with mpox and developed proctitis-associated bowel obstruction, urinary retention, and eosinophilia. Our case highlights potential gastrointestinal manifestations of severe mpox infection.

Contrast-enhanced US Evaluation of Endoleaks after Endovascular Stent Repair of Abdominal Aortic Aneurysm.

Ruptured abdominal aortic aneurysm (AAA) carries high morbidity and mortality. Elective repair of AAA with endovascular stent-grafts requires lifetime imaging surveillance for potential complications, most commonly endoleaks. Because endoleaks result in antegrade or retrograde systemic arterialized flow into the excluded aneurysm sac, patients are at risk for recurrent aneurysm sac growth with the potential to rupture. Multiphasic CT has been the main imaging modality for surveillance and symptom evaluation, but contrast-enhanced US (CEUS) offers a useful alternative that avoids radiation and iodinated contrast material. CEUS is at least equivalent to CT for detecting endoleak and may be more sensitive. The authors provide a general protocol and technical considerations needed to perform CEUS of the abdominal aorta after endovascular stent repair. When there are no complications, the stent-graft lumen has homogeneous enhancement, and no contrast material is present in the aneurysm sac outside the stented lumen. In patients with an antegrade endoleak, contrast material is seen simultaneously in the aneurysm sac and stent-graft lumen, while delayed enhancement in the sac is due to retrograde leak. Recognition of artifacts and other potential pitfalls for CEUS studies is important for examination performance and interpretation.

Imaging evaluation for the diagnosis and management of complications of gender-affirming surgeries.

Gender-affirming surgeries (GS) allow transgender individuals to align their physical sexual characteristics with their gender identity, which can result in profound changes to native anatomy. Medical imaging is a useful tool for evaluation of patients who have undergone or plan to pursue GS. Given the complex nature of some GS, complications may arise. The choice of imaging modality can be guided by the clinically suspected complications. For example, urethral complications of phalloplasty are best evaluated with fluoroscopic urethrography. Pelvic magnetic resonance imaging provides detailed depiction of pelvic neo-anatomy after vaginoplasty. Many GS involve the creation of vascular pedicles for tissue grafts, which are at risk of thrombosis and graft ischemia. Doppler ultrasound and computed tomography (CT) angiography are important for diagnosis of these dreaded complications. Moreover, interventional radiologists may participate in endovascular treatments for such complications. Various imaging modalities may assist the surgeon in the postoperative evaluation of patients with suspected complications after GS, and imaging protocol modifications may be required to improve diagnostic accuracy. For example, rectal or neovaginal contrast material may be necessary to ensure accurate imaging evaluation, such as delineation of fistulas. Working together, surgeons and radiologists can ensure accurate imaging assessment while accommodating for patient comfort.

Undifferentiated embryonal sarcoma of the liver presenting as a hemorrhagic mass in a pregnant woman.

We present a case of undifferentiated embryonal sarcoma of the liver (UES), an uncommon malignant mesenchymal tumor that occurs predominately in children and is very rarely seen in adults. Our patient is a 32-year-old pregnant female without significant past medical history, who presented to the emergency department with worsening abdominal pain and a large palpable abdominal mass. Imaging identified a large, hemorrhagic right hepatic lobe mass that in retrospect had imaging characteristics most suggestive of UES. Though extremely rare in adults, it is still important to recognize the imaging features of UES as to avoid mistaking it for other more common benign and malignant hepatic masses.

Comparative accuracy of preoperative tumor size assessment on mammography, sonography, and MRI: Is the accuracy affected by breast density or cancer subtype?

PURPOSE: To compare the accuracy of preoperative breast tumor size measurements obtained on three imaging modalities (mammography [MM], sonography [US], and MRI) with those obtained on final pathologic examination for different breast densities and various tumor types. METHODS: Records from patients who underwent breast cancer lumpectomy between 2008 and 2012 and in whom tumor was seen on all three imaging modalities were retrospectively reviewed for maximum tumor size measurements. Patients with positive tumor margins and those who had undergone neoadjuvant chemotherapy were excluded. Tumor size measurements obtained on the three imaging modalities were compared for accuracy with those obtained during the final pathologic examination. Differences were analyzed for the whole group and for subgroups according to breast density and tumor type. RESULTS: In total, 57 patients were included, in whom wire-localization lumpectomy was performed without neoadjuvant chemotherapy; negative surgical margins for tumor were obtained, and tumor was preoperatively visualized on all three imaging modalities. The mean (± SEM) tumor size measured on MRI was significantly greater than that measured on pathology (p < 0.001), whereas the sizes measured on US and MM were not statistically significantly different from that measured on pathology (p = 0.62 and p = 0.57). Tumor size measured on MRI was greater than that measured on both US and MM (p = 0.003 and p < 0.001). Compared with the measurements obtained on pathology, that obtained on US showed moderate agreement (Lin concordance correlation coefficient [CCC], 0.71; 95% confidence interval [CI], 0.56-0.82); poorer agreement was found for the sizes obtained on MM (CCC, 0.58; 95% CI, 0.38-0.72) and MRI (CCC, 0.50; 95% CI, 0.31-0.65). No difference in comparative accuracy of size measurement was noted between dense and nondense breast tissue. MRI overestimated tumor size in ductal cancers (p < 0.001) and slightly underestimated it in lobular cancers. CONCLUSIONS: Preoperative MRI significantly overestimated tumor size. Measurements obtained on US and MM were more accurate irrespective of breast density, with US measurements being slightly more accurate than MM measurements.
