Exploring the landscape of automated species identification apps: Development, promise, and user appraisal.

Two decades ago, Gaston and O'Neill (2004) deliberated on why automated species identification had not become widely employed. We no longer have to wonder: This AI-based technology is here, embedded in numerous web and mobile apps used by large audiences interested in nature. Now that automated species identification tools are available, popular, and efficient, it is time to look at how the apps are developed, what they promise, and how users appraise them.

Multi-parametric magnetic resonance imaging assessment of whole tumour heterogeneity for chemoradiotherapy response prediction in rectal cancer.

Background And Purpose: Prediction of chemoradiotherapy response (CRT) in locally advanced rectal cancer would enable stratification of management. The purpose was to prospectively evaluate multi-parametric magnetic resonance imaging (MRI) assessment of tumour heterogeneity combining diffusion weighted imaging (DWI) and dynamic contrast enhanced (DCE) MRI for the prediction of CRT response in locally advanced rectal cancer.

Materials And Methods: Patients with Stage II or III rectal adenocarcinoma undergoing neoadjuvant CRT and surgery underwent MRI (DWI and DCE) before, during (week 3), and after CRT (1 week before surgery).

Dural metastasis demonstrated on Tc-99m MDP bone scintigraphy in staging workup for a patient with breast cancer.

An 80-year-old woman with multifocal invasive lobular carcinoma of the right breast treated 6 years previously with mastectomy, locoregional radiotherapy, and tamoxifen was referred for a bone scan to investigate generalized arthralgias. The patient reported right-sided headaches, blurred vision, and dizziness in the previous 3 months. The bone scan revealed a large area of unusual and abnormal Tc-99m methylene diphosphonate (MDP) uptake in the right frontoparietal skull region.

Renal scintigraphy unraveled the diagnostic dilemma of antenatal hydronephrotic solitary kidney-crossed renal ectopia.

On antenatal ultrasound assessment, an apparently solitary hydronephrotic kidney was identified, confirmed on postnatal ultrasound examination. More detailed postnatal investigations revealed the diagnosis of crossed renal ectopia.
