Fetal and placental anatomy visualized with cinematic rendering from volumetric CT data
Avoiding unnecessary radiation exposure in children, including fetuses or embryos, is of paramount importance. However, emergent clinical situations will arise that necessitate the use of ionizing radiation-based modalities, such as computed tomography (CT), in this patient population. In such…

Molecular imaging in oncology: Current impact and future directions
The authors define molecular imaging, according to the Society of Nuclear Medicine and Molecular Imaging, as the visualization, characterization, and measurement of biological processes at the molecular and cellular levels in humans and other living systems. Although practiced for many years…

A three-stage, deep learning, ensemble approach for prognosis in patients with Parkinson’s disease
Abstract Background Diagnosis of Parkinson’s disease (PD) is informed by the presence of progressive motor and non-motor symptoms and by imaging dopamine transporter with [123I]ioflupane (DaTscan). Deep learning and ensemble methods have recently shown promise in medical image analysis. Therefore…

Relationship between DXA measured metrics of adiposity and glucose homeostasis; An analysis of the NHANES data.
INTRODUCTION:Obesity is associated with insulin resistance and type 2 diabetes. Dual-energy X-ray absorptiometry (DXA) is a means of determining body composition and body fat distribution at different sites including whole body and trunk-locations where there tends to be high correlation at an…

Theranostics in Oncology—Thriving, Now More than Ever
Tracing its roots back to the 1940s, theranostics in nuclear oncology has proved successful mainly due to the beneficial effects of image-guided therapeutic concepts for patients afflicted with a variety of different cancers. The majority of these treatments are not only characterized by…

Renal Pseudoaneurysm Mimicking Local Cancer Recurrence After Partial Nephrectomy
The development of an iatrogenic vascular lesion, such a renal pseudoaneurysm or arteriovenous fistula, is a rare complication of partial nephrectomy. These lesions should be considered in patients presenting with an enhancing mass in the resection bed shortly following partial nephrectomy. Early…

Incidental primary breast cancer detected on surveillance 68Ga-DOTATATE PET/CT in a patient with metastatic neuroendocrine carcinoma
We present a case of a 53-year-old woman with metastatic neuroendocrine tumor, presumed primary in the small intestine with metastases to the liver and mesenteric lymph nodes. The patient was being treated with lanreotide and followed with somatostatin receptor (SSTR)-targeted 68Ga-labeled…

Dynamic Contrast Enhanced-MR CEST Urography: An Emerging Tool in the Diagnosis and Management of Upper Urinary Tract Obstruction
Upper urinary tract obstructions (UTOs) are blockages that inhibit the flow of urine through its normal course, leading to impaired kidney function. Imaging plays a significant role in the initial diagnosis of UTO, with anatomic imaging (primarily ultrasound (US) and non-contrast computed…

Prostate multi-parametric magnetic resonance imaging appearance of diffuse adenosis of the peripheral zone (DAPZ)
Imaging specialists must recognize potential mimics of prostate cancer (PCa) on multi-parametric magnetic resonance imaging (mpMRI). We describe the appearance of diffuse adenosis of the peripheral zone (DAPZ) on mpMRI. The features of DAPZ parallel those of diffuse PCa, with low signal on…

Uptake of prostate-specific membrane antigen-targeted 18F-DCFPyL in avascular necrosis of the femoral head
In recent years, the emergence of prostate-specific membrane antigen (PSMA)-targeted positron-emission tomography (PET) imaging has brought about a paradigm shift in the way that prostate cancer (PCa) is imaged in many parts of the world. Although PSMA-targeted PET imaging has been demonstrated to…

Automated lesion detection of breast cancer in [18F] FDG PET/CT using a novel AI-Based workflow
Applications based on artificial intelligence (AI) and deep learning (DL) are rapidly being developed to assist in the detection and characterization of lesions on medical images. In this study, we developed and examined an image-processing workflow that incorporates both traditional image…

Vas deferens infiltration by prostate cancer on prostate-specific membrane antigen-targeted 18F-DCFPyL positron emission tomography/computed tomography: A unique visual pattern
New radiotracers for positron emission tomography imaging that target prostate-specific membrane antigen (PSMA) have emerged as important clinical tools for imaging prostate cancer (PCa). PSMA-targeted radiotracers have demonstrated high sensitivity and high specificity for detecting sites of PCa…

Evidence of anorectal involvement by prostate cancer on GA-68-PSMA-11 PET/CT portends inguinal nodal metastasis
Biochemical recurrence was detected in a 68-year-old diagnosed with prostate adenocarcinoma 6 years previously (Gleason 4+4=8, grade group 4, T1bN0M0) status post radiation therapy and 2 years of androgen-deprivation therapy. The patient underwent transurethral resection of the prostate (TURP) for…

Acute axillary lymphadenopathy detected shortly after COVID-19 vaccination found to be due to newly diagnosed metastatic melanoma
As the administration of COVID-19 vaccines continues to increase, so too does awareness of the associated ipsilateral axillary lymphadenopathy. This has created a diagnostic challenge in the field of radiology, in particular among patients with cancer, as post-vaccination reactive adenopathy has…
