Article Synopsis
- This study explores the impact of false-negative F-FDG PET/CT results in patients with multiple myeloma (MM), particularly those with low expression of hexokinase-2 (HK2), which may influence diagnosis and treatment outcomes.
- Researchers analyzed 90 newly diagnosed MM patients during induction therapy and categorized them based on PET/CT and diffusion-weighted MRI results, identifying a group with false-negative PET/CT results.
- Findings revealed that patients with false-negative PET/CT had better prognosis indicators, such as longer time to next treatment and progression-free survival, suggesting that low HK2 expression might indicate lower disease risk despite misleading PET/CT results.
Pretreatment F-FDG PET/CT combined with quantification of clonal circulating plasma cells as a potential risk model in patients with newly diagnosed multiple myeloma.

Purpose: Both F-FDG PET/CT and clonal circulating plasma cell (CPC) quantification are emerging tools for multiple myeloma (MM) prognostication that have been validated in recent studies. This study investigated the value of PET/CT coupled with CPC quantification for MM prognostication that may contribute to future risk-adapted treatment.
Methods: We retrospectively analysed the prognostic relevance of a combination of pretreatment PET/CT findings and CPC levels in 163 consecutive patients with newly diagnosed, symptomatic MM receiving novel agents during induction therapies.
Recognizing imaging characteristics after ophthalmic surgery is necessary for radiologists to prevent misdiagnosis. We review typical appearances of intraorbital implanted devices and materials on CT and MRI with demonstration of the common surgical procedures. EX-PRESS glaucoma filtration devices appear as punctate areas of metal attenuation on CT and are typically placed at the corneoscleral junction.

The purpose of this study is to clarify the features of PTA and its variants (PTAV) based on a large magnetic resonance angiography (MRA) series.
Methods: MRA was performed on continuous 16,415 patients (8,610 males and 7,805 females) between October 2005 and September 2008 using two 1.
