Intra-procedural assessment of reperfusion during mechanical thrombectomy (MT) for emergent large vessel occlusion (LVO) stroke is traditionally based on subjective evaluation of digital subtraction angiography (DSA). However, semi-quantitative diagnostic tools which encode hemodynamic properties in DSAs, such as angiographic parametric imaging (API), exist and may be used for evaluation of reperfusion during MT. The objective of this study was to use data-driven approaches, such as convolutional neural networks (CNNs) with API maps, to automatically assess reperfusion in the neuro-vasculature during MT procedures based on the modified thrombolysis in cerebral infarction (mTICI) scale.

DSAs from patients undergoing MTs of anterior circulation LVOs were collected, temporally cropped to isolate late arterial and capillary phases, and quantified using API peak height (PH) maps. PH maps were normalized to reduce injection variability. A CNN was developed, trained, and tested to classify PH maps into 2 outcomes (mTICI 0,1,2a/mTICI 2b,2c,3) or 3 outcomes (mTICI 0,1,2a/mTICI 2b/mTICI 2c,3), respectively. Ensembled networks were used to combine information from multiple views (anteroposterior and lateral).

The study included 383 DSAs. For the 2-outcome classification, average accuracy was 81.0% (95% CI, 79.0-82.9%), and the area under the receiver operating characteristic curve (AUROC) was 0.86 (0.84-0.88). For the 3-outcome classification, average accuracy was 64.0% (62.0-66.0), and AUROC values were 0.85 (0.83-0.87), 0.74 (0.71-0.77), and 0.78 (0.76-0.81) for the mTICI 0,1,2a, mTICI 2b, and mTICI 2c,3 classes, respectively.

This study demonstrated the feasibility of using hemodynamic information in API maps with data-driven models to autonomously assess intra-procedural reperfusion during MT.

Histological findings of pulmonary drug reactions can mimic other conditions such as various forms of idiopathic interstitial pneumonia such as nonspecific interstitial pneumonia, organizing pneumonia, diffuse alveolar damage, or usual interstitial pneumonia. The correct diagnosis is important since a causal therapy is possible by stopping the administration. A stringent correlation between dose/time of administration and the type of reaction exists for only a few drugs. An increased risk of drug side effects can arise from known reactions to that specific drug, the patient's history, the type of underlying disease, genetic polymorphisms, occupational factors, and interactions with other drugs. The identification of a pulmonary drug reaction is a difficult task that can often only be solved in an interdisciplinary manner, for which in rare cases a lung biopsy is necessary. Pathology then has to identify histomorphological reaction patterns to exclude other causes and correlate findings with clinical data. In most cases, however, the diagnosis of a drug reaction will be by exclusion.The current edition of the WHO classification of thyroid tumors (2017) contains a number of very relevant changes with considerable consequences for the diagnostic assessment of thyroid specimens. This applies to both the histomorphological examination of surgical specimens and the preoperative fine needle biopsy (FNB). In addition, molecular pathological examinations are becoming increasingly important in the diagnosis of thyroid tumors. Changes affect practically all areas of thyroid tumor diagnostics. Some of these changes have far-reaching consequences that justify a comprehensive commentary and query of the knowledge acquired in the form of this CME article.Patients with otosclerosis can suffer from different grades of combined hearing loss. In addition to surgery (stapedectomy), conventional hearing aids can be used in the treatment of otosclerosis. In cases of severe conductive components in addition to sensorineural hearing loss, treatment with normal hearing aids can be difficult or impossible. In these patients, implantable hearing systems such as cochlear implants represent a possible alternative. The totally implantable Carina middle ear system can be used in patients with even high-grade sensorineural hearing loss. Based on two exemplary cases, the option of using the Carina system in otosclerosis patients and post-implantation results are reported.The Singapore Health Services cluster (SingHealth) radiology film archives are a valuable repository of local radiological cases dating back to the 1950s. Some of the cases in the archives are of historical medical interest, i.e. cerebral angiography in the workup of patients with hemiplegia. Other cases are of historical social interest, being conditions seen during earlier stages of Singapore's development, i.e. bound feet. The archives form a unique portal into the development of local radiology as well as the national development of Singapore. A selection from the archives is published in 2020 in commemoration of the 20th anniversary of the formation of SingHealth, the 55th National Day of Singapore, and the 125th anniversary of the International Day of Radiology. This pictorial essay comprises cardiovascular, respiratory and neurological cases from the archives.The Unified Interaction Model (UNIM) simulates the linear/supralinear dose response of the glow peaks of LiFMg,Ti (TLD-100) and other thermoluminescent materials and the dependence of the supralinearity on photon/electron energy. The UNIM is based on the radiation action of spatially correlated trapping centres (TCs) and luminescent centres (LCs), which results in localised (geminate) electron/hole recombination by quantum mechanical tunnelling. check details The linear dose response is mainly attributed to geminate recombination. UNIM simulations of the dose response of glow peak 5 in LiFMg,Ti following 500 and 8 keV electron/photon irradiation are discussed. In addition, simulations of postirradiation photo-excitation that redistribute the electrons and holes in the various TCs and LCs are demonstrated to extend the region of linear dose response and reduce the supralinearity. Experimental verification of dose-response linearity for levels of dose ≤30 Gy following both 3.65 and 5 eV photon excitation is presented.
