PACS' efficiency leaves more time for research and education
Administration, education and research may all become more efficient as teaching hospitals implement PACS, according to researchers from the University of Maryland Medical Center in Baltimore. Dr. Barry Daly presented the results of a study examining the influences of PACS on non-clinical activities in an academic medical center at last month's RSNA conference in Chicago.

UCLA hospital to be paperless and filmless
CHICAGO - The University of California Los Angeles is in the process of building a new acute-care hospital, due to open in 2005, with the intent to operate on a fully digital basis. According to a presentation at this week’s RSNA meeting, the plan for this hospital is based on a goal of facility-wide, more efficient access to all information sources.

Cardiac nuclear imaging: Who owns the procedure?
CHICAGO – According to presenters at the RSNA Monday, cardiologists are performing the lion’s share of cardiac nuclear imaging (CNI) procedures in the U.S. In a pair of papers presented here, researchers at Thomas Jefferson University in Philadelphia discussed the declining role of radiologists in CNI.

MRA use advised in conjunction with DUS
CHICAGO - Researchers from the Glasgow Royal Infirmary in Scotland found the high level of disagreement between the findings of duplex ultrasound (DUS) and MR angiography (MRA) can be mostly attributed to the limitations of duplex ultrasound in visualizing calcified vessels or difficult anatomy.

Images of a 39-year-old who underwent screening mammography. Right craniocaudal (left) and mediolateral oblique (middle) views from preoperative mammography show suspicious grouped fine pleomorphic calcifications (arrows). After biopsy showed ductal carcinoma of situ (DCIS), patient underwent breast-conserving surgery, yielding final diagnosis of ductal carcinoma in situ (intermediate grade, hormone receptor positive). (Right) Screenshot of an output of a commercial AI tool applied to preoperative mammography. AI detected right breast lesion with score of 95% on both views (concentric colored circles).

Axial contrast-enhanced CT scan in a 28-year-old premenopausal woman shows an incidentally detected solid-appearing left ovarian lesion (solid arrow) anterior to the uterus (U), associated with trace ascites in the right adnexa and cul de sac (dashed arrows). At pathologic analysis, this was shown to be ovarian dysgerminoma. Two readers misdiagnosed this lesion, one as a leiomyoma and one as an ovarian fibroma.

PET/CT reveals new infections in ICU patients
By Will Morton
F-18 FDG-PET/CT is a valuable approach for diagnosing unknown infections in intensive care unit (ICU) patients.
February 21, 2025
There are several conceivable advantages of F-18 FDG PET/CT over conventional imaging. Image A and B showing an example of the distinctive capability of the F-18 FDG PET/CT. A shows a fusion image of F-18 FDG PET/CT and low-dose CT and B an high resolution chest CT of a patient with an Aspergillus infection. The suspected aspergilloma is concealed on the high resolution CT due to the lung fluids and consolidation. Image C and D (fusion image of F-18 FDG PET/CT and low-dose CT and low-dose CT only, respectively) are examples of the ability to image inflammation while no concurrent abnormalities are visualized, in this case prostatitis (red arrows). Image E, a maximized intensity projection of F-18 FDG PET, shows a patient with lung infections and multiple muscle abscesses after MRSA sepsis. This is an illustrative example of a relevant dissemination investigation.

1Each lung has been split into three parts. Each area has been given a score between 0 and 3. Score values are shown in Ultrasonograms to match 4 different patterns. During a longitudinal scan with a high-resolution linear probe, pictures of patterns were taken. The scores are as follows: 0 means A pattern, 1 means B pattern, 2 means severe B pattern, and 3 means extended consolidation.

(B and C) Low uptake of Ga-68 PSMA-R2 in salivary and submandibular glands is also demonstrated. (D) Images show heterogeneous uptake of Ga-68 PSMA-R2 with varying degrees of intensity in multiple spine bone lesions (vertebral sclerotic lesion with intense PSMA-R2 expression at its periphery indicated with red arrow).

CT best for diagnosing suspected wooden foreign objects in the eye
By Kate Madden Yee
CT imaging is best for diagnosing suspected intraorbital wooden foreign bodies, although MR imaging does offer valuable supplementary information.
February 20, 2025
A 7-year-old boy, imaged 15 hours post-injury. Axial CT images with soft tissue windows (WW/WL=350/50) (a) reveal a rod-shaped foreign body (white arrow) situated along the course of the right inferior rectus muscle. The soft tissue window demonstrates that the foreign body exhibits attenuation similar to orbital emphysema. Axial CT images (WW/WL=1000/−200) at the same level (b) show that the attenuation of the foreign body (white arrow) is markedly different from that of the air in the sinuses.
