'Pleased to meet you' -- academic imaging center moves market with personal touch
CHICAGO - The explosion of independent freestanding diagnostic imaging centers in the U.S. has meant a steady encroachment on patient volume with a decrease in outpatient revenue for academic-based radiology groups. An academic practice from Brown University in Providence, RI, met this challenge head-on by creating and implementing a successful marketing campaign.

MR, PET/CT show low sensitivity for melanoma
CHICAGO - A significant number of patients with malignant melanoma of the skin initially staged as negative for lymph node and distant metastases with whole-body MRI and PET/CT eventually proved to have undetected regional or distant metastases, according to researchers from the department of radiology at the University Hospital of Essen in Germany.

PACS plus paperless proves powerful
CHICAGO - PACS' capability to streamline the workflow process has increased radiologist efficiency for many institutions. Taking paper out of the picture can result in an even greater increase in time savings, according to researchers from the University of Pittsburgh Medical Center in Pennsylvania.

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.

By Amerigo Allegretto
Lung ultrasound (LUS) scoring is reliable for determining whether preterm newborns need surfactant for suspected respiratory distress syndrome (RDS).
February 20, 2025
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.

PSMA-PET tracer performs well in clinical trial

(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.
