Aplasia Cutis Congenita in an Infant with Very Low Birth Weight

A female neonate was born with 2 congenital defects of the skin and bone on her head. She was born at 35  weeks and 3 days of gestation with a birth weight of 1484 g (−2.92 SD). Apgar scores were 8 and 9 at 1 and 5 minutes, respectively. At 34 weeks of gestation, a wide part of the scalp and skull, from the parietal to the occipital region, was noted to be absent on ultrasound and fetal magnetic resonance imaging Therefore, skull aplasia of the fetus was suspected (Figure 1; available at www.jpeds.com).

We hypothesized that valgus stress ultrasound would be useful for both identifying medial ulnar collateral ligament (MUCL) tears and assessing the severity of the tears. Hence, we performed valgus stress ultrasound of the elbow in athletes with MUCL  injuries, confirmed by magnetic resonance imaging (MRI), to determine whether ultrasound can be used as a diagnostic tool.

ConclusionIn patients with PSA serum levels of 4∼10 ng/mL, bpMRI and bpMRI combined with PSAD achieve better performance than mpMRI in detecting csPCa; bpMRI has a higher specificity than mpMRI, which could decrease unnecessary biopsy, and may serve as a potential alternative to mpMRI to optimize clinical workup.

ConclusionNormal sizes and signal intensities for adrenal glands are reported. Visibility of adrenal glands on T2-W images was 90.3 –97.2% up to 30 weeks but declined thereafter. Visibility on T1-W images increased in the third trimester. Adrenal gland sizes increased with gestational age.

This article discusses the 4 main imaging modalities used to evaluate reproductive-aged women: ultrasound, magnetic resonance imaging, computed tomography, and fluoroscopy. For each modality, major clinical indications are described, along with important technical considerations unique to imaging reproductive-aged women. Finally, key safety issues are discussed, particularly with regard to imaging pregnant patients. PMID: 32044002 [PubMed - in process]

The epidemic of increasing fatty liver disease and liver cancer worldwide, and especially in Western society, has given new importance to non-invasive liver imaging. Contrast-enhanced ultrasound (CEUS) using microbubble contrast agents provides unique advantages over computed tomography (CT) and magnetic resonance imaging (MRI), the currently established methods. CEUS provides determination of malignancy and allows excellent differential diagnosis of a focal liver mass, based on arterial phase enhancement patterns and assessment of the timing and intensity of washout.

CONCLUSION:  Based on the results of the analysis, the use of CEUS was identified as a cost-effective diagnostic strategy for the characterization of incidentally found cystic renal lesions. PMID: 32052386 [PubMed - as supplied by publisher]

ConclusionThere is increasing evidence that DTI is superior to conventional targeting methods with respect to improving brain stimulation therapies. DTI has the ability to better define anatomical targets by allowing detailed visualization of white matter tracts and localizing targets based on individual anatomy. Network analyses can lead to the identification of new or optimal stimulation targets based on understanding how target regions are connected. The integration of DTI as part of routine MRI and surgical planning offers a more personalized approach to therapy and may be an important path for the future of neuromodulation.

Abstract For much of the 1990s, transrectal ultrasound systematic biopsy was the standard approach for prostate cancer diagnosis. However, in the past decade multiparametric magnetic resonance imaging, multiparametric ultrasound and image fusion targeting have come to the fore. Here we present the state-of-the-art diagnostic strategies in prostate cancer detection and examine the case for target-only biopsy, as well as the benefits and limitations.

The urachus revisited: Multimodal imaging of benign &malignant urachal pathology. Br J Radiol. 2020 Feb 11;:20190118 Authors: Das JP, Vargas HA, Lee A, Hutchinson B, O'Connor E, Kok HK, Torreggiani W, Murphy J, Roche C, Bruzzi J, McCarthy P Abstract The urachus is a fibrous tube extending from the umbilicus to the antero superior bladder dome that usually obliterates at week 12 of gestation, becoming the median umbilical ligament. Urachal pathology occurs when there is incomplete obliteration of this channel during foetal development, resulting in the formation of a urachal cyst, patent urachus, u...

Abstract Multiparametric magnetic resonance imaging (mpMRI) has been increasingly used to diagnose clinically significant prostate cancer (csPC) because of its usefulness in combination with anatomic and functional data. MRI-targeted biopsy, such as MRI-transrectal ultrasound (TRUS) fusion image-guided prostate biopsy, has high accuracy in the detection and localization of csPC. This novel diagnostic technique contributes to the development of tailor-made medicine as focal therapy, which cures the csPC while preserving the anatomical structures related to urinary and sexual function. In the early days of focal the...
