What “Brain scans and imaging” covers

Brain scans and imaging — MRI, PET and other scans: what they show, how early, and how reliably.

A note on reading research. One study is rarely the final word.

We try to note the size of a study, whether it was in humans or animals, and how early-stage the finding is. If a summary here doesn't make that clear, treat it with extra caution and check the original source.

Alzheimer Hastalığının Tespiti CNN Model Sınıflandırması

✓ Peer-reviewed alzhub usefulness score 29 out of 100. International Journal of Pure and Applied Sciences 2025-06-27

Bilgisayar destekli cihaz ve sistemlerin sağlık sektöründe giderek artan kullanımı, hastalıkların daha erken ve daha hızlı teşhis edilmesine olanak sağlamaktadır. Bilgisayar destekli sistem ve cihazlar özellikle nörolojik hastalıkların tanı ve görüntülemesinde kritik bir rol oynamaktadır. Merkezi sinir sistemi ve bilişsel fonksiyonların değerlendirilmesindeki gelişmeler, özellikle Alzheimer Hastalığı gibi nörodejeneratif hastalıkların erken teşhisinde önemli avantajlar sağlamaktadır. Çalışmada kullanılan veriler Kaggle platformunda açık kaynaklı olarak bulunan “Augmented Alzheimer MRI Dataset” isimli veri setinden alınmıştır. Bu veri setinde ikinci klasör kullanılmıştır. Toplamda 33.894 adet görüntü bulunmaktadır. Çalışmada Alzheimer hastalığı teşhisi analizi için derin öğrenme sınıflandırıcı model olarak Convolutional Neural Network (CNN) kullanılmıştır.

How the 0–100 score works — and why some entries are capped

This is alzhub's own score. It is not an official metric, not an impact factor, and no journal, publisher or ranking body endorses it. We built it so that a reader who is not a scientist can tell a landmark trial from a conference abstract without having to already know the difference. Every point comes from one of 20 components, all of them printed on the study itself, so you can disagree with our arithmetic rather than having to trust the total.

Journals are placed in ordered tiers, never given a numeric impact factor — we could not verify current impact factors from a source we control, and an invented one would be worse than none. Tier 1 is the top-tier general journals (NEJM, The Lancet, JAMA, Nature, Science, Nature Medicine); tier 2 is the leading specialty journals; tier 3 is every other peer-reviewed journal. A separate part scores how much the journal's own papers are cited, which tells the tier-3 journals apart.

Two rules we don't bend. First, we never fill in a missing value: if a record does not state a sample size or a design, that component scores zero, and if we simply have no data for a part, such as a citation count, that part is left out and the study is scored on the parts we could check. The study card says which. Second, anything that is not a peer-reviewed article is capped at 16/100 and carries a warning chip — so a conference abstract or a company press release can never outrank a peer-reviewed paper, no matter how good it looks.

We rank a rigorous null result — a good trial showing that something does not work — above an early positive finding. Someone deciding whether to buy a supplement is served by that, and the rigour is already counted by the design and journal components.

The score is computed from the published data alone and is reproducible: the same file always yields the same numbers.

See the whole rubric drawn out → — four charts covering all 27,380 studies: how the scores are spread and where the cap bites, which of the 20 components the library is strong and weak on, which subjects rest on stronger evidence, and what kinds of study each subject is actually built from.

What this library is — and isn't

This is a large sample of the Alzheimer's literature, not an exhaustive index of it. It holds 27,380 records, built mostly from automated pulls of Europe PMC (60.6% of the library) and OpenAlex (18.6%), plus smaller pulls from PubMed, Crossref and medRxiv. If a study, a drug, or a finding isn't here, that is not evidence it doesn't exist in the literature — it may simply not have been pulled in yet.

1,032 records (3.8% of the library) are not peer-reviewed — 962 of those are preprints posted before any journal review, and the rest are conference abstracts, regulatory notices and reports. Every study card on this page states its status plainly, and the score above is capped for anything that isn't a peer-reviewed article.
