Americans have been receiving contradictory information about the coronavirus pandemic, so much so that it's become a joke. One example is face masks: In March, the World Health Organization advised people to not wear masks if they aren't sick or caretakers of the sick. 

But given that some coronavirus patients are asymptomatic, opinions of masks from top officials have shifted. The CDC and the media now advise you to wear a damn mask. And a new study may provide more evidence that masks can help beat the outbreak.

According to this study, if 80 percent of Americans wore masks, coronavirus infections would plummet, Vanity Fair reports. The title of the study makes the researchers' view clear: Universal Masking is Urgent in the COVID-19 Pandemic. Read more...

Respiratory motion during the CT and PET parts of a PET/CT scan leads to imperfect alignment of anatomical features seen by the two modalities. In this work, we concentrate on the effects of motion during CT. We propose a novel approach for improving the alignment. Methods: Respiratory waveform data were gathered during the CT and PET parts of 28 PET/CT scans of cancer patients with 40 lesions up to 3 cm size in the lung or upper abdomen. PET list-mode data were reconstructed by three reconstruction methods: PET/static, PET/EX or end of expiration (OncoFreeze), and a novel PET/matched method that used both waveforms. The three methods were compared. The distance between tumor positions in PET and CT were characterized in visual interpretation by physicians as well as quantitatively. Tumor standardized uptake values (SUV_max and SUVpeak) were determined relative to SUV based on the static method. Image noise was evaluated in the liver and compared to PET/static. Results: In visual interpretation, the rate of good alignment was 13/21, 13/23 and 18/21 for PET/static, PET/EX and PET/matched methods, respectively, and the mean PET-CT distances were 3.5, 5.1 and 2.8 mm. In visual comparison with PET/EX, the rate of good alignment was increased in 1/10 and 7/10 cases for PET/static and PET/matched. SUV_max was on average 21% higher than PET/static when either PET/EX or PET/matched was used. SUVpeak was 12% higher. Image noise in the liver was 15% higher than static for the PET/EX method, and 40% higher for PET/matched; that is, noise was much lower than in gated PET. Conclusion: Acquiring respiratory waveforms both in PET (as in the current state of the art) and in CT (an unusual key step in this approach) has the potential to improve the alignment of PET and CT images. A proposed method for using this information was tested. Improved alignment was demonstrated.

Purpose: The main objective of this prospective study was to determine the impact of multi-phasic acquisition of ⁶⁸Ga-PSMA PET/CT in the detection of recurrent prostate cancer (PCa) in the early stage of biochemical recurrence (BR) with prostate-serum-antigen (PSA) level <1ng/ml. Also, ⁶⁸Ga-PSMA PET/CT positivity was correlated with clinical parameters for the assessment of predictive markers. Methods: A prospective monocentric study was conducted on 135 PCa patients with BR and PSA<1ng/ml. All patients have undergone initial prostatectomy with additional radiation therapy in 19.3% and androgen-deprivation therapy (ADT) in 7.4% of patients. Dynamic acquisition [1–8min. post-injection (p.i.)] from the prostate bed, standard whole-body (60min. p.i.) and limited bed positions of delayed studies (120-150min. p.i.), were performed. Studies were reviewed by two board-certified nuclear medicine specialists, independently. A combination of visual and semi-quantitative analyses and correlation with morphological (e.g. MRI) and/or clinical follow-up findings was used for the final interpretation of abnormal lesions as benign or malignant. ⁶⁸Ga-PSMA PET/CT positivity was also correlated with primary clinical findings. Results: Incorporating the information of all phases, 116 lesions were detected in 49.6% of patients (22 local recurrences, 63 lymph nodes, and 31 distant metastases). The detection rates were 31.8%, 44.9%, and 71.4% for PSA<0.2ng/ml, 0.2≤PSA<0.5, and 0.5≤PSA<1, respectively. Additional dynamic and/or delayed phases resulted in better determination of equivocal lesions and a higher diagnostic performance in 25.9% of patients. Stand-alone dynamic and delayed images led to better interpretation of equivocal findings in the prostate bed (31.4%) and other (lymph node/bone) lesions (20%), respectively. Conclusion: ⁶⁸Ga-PSMA PET/CT revealed promising results for the early detection of recurrent disease in patients with PSA level of 0.5-1.0ng/ml. However, it showed limited value in cases with PSA<0.5ng/ml. Multi-phasic ⁶⁸Ga-PSMA PET/CT led to better determination of equivocal findings. Although, dynamic images may provide helpful information in assessment of the prostate bed; however, delayed acquisitions seem to have higher impact in clarifying of the equivocal findings.

Abstract:
Transformation based Markov Chain Monte Carlo (TMCMC) was proposed by Dutta and Bhattacharya ( Statistical Methodology 16 (2014) 100–116) as an efficient alternative to the Metropolis–Hastings algorithm, especially in high dimensions. The main advantage of this algorithm is that it simultaneously updates all components of a high dimensional parameter using appropriate move types defined by deterministic transformation of a single random variable. This results in reduction in time complexity at each step of the chain and enhances the acceptance rate. In this paper, we first provide a brief review of the optimal scaling theory for various existing MCMC approaches, comparing and contrasting them with the corresponding TMCMC approaches.The optimal scaling of the simplest form of TMCMC, namely additive TMCMC , has been studied extensively for the Gaussian proposal density in Dey and Bhattacharya (2017a). Here, we discuss diffusion-based optimal scaling behavior of additive TMCMC for non-Gaussian proposal densities—in particular, uniform, Student’s $t$ and Cauchy proposals. Although we could not formally prove our diffusion result for the Cauchy proposal, simulation based results lead us to conjecture that at least the recipe for obtaining general optimal scaling and optimal acceptance rate holds for the Cauchy case as well. We also consider diffusion based optimal scaling of TMCMC when the target density is discontinuous. Such non-regular situations have been studied in the case of Random Walk Metropolis Hastings (RWMH) algorithm by Neal and Roberts ( Methodology and Computing in Applied Probability 13 (2011) 583–601) using expected squared jumping distance (ESJD), but the diffusion theory based scaling has not been considered. We compare our diffusion based optimally scaled TMCMC approach with the ESJD based optimally scaled RWM with simulation studies involving several target distributions and proposal distributions including the challenging Cauchy proposal case, showing that additive TMCMC outperforms RWMH in almost all cases considered.
