T1 Weighted (T1W)

B

FLAIR (Fluid Attenuated Inversion Recovery)

C

T2 Weighted (T2W)

B

Coronal

C

Sagittal

D

All

E

Other

How do you determine the severity of atrophy (e.g., mild, moderate, severe) ?

*

(You can write more than one with "Other" option, if you don't use scoring systems or measurements you can skip 7th and 8th questions.)

A

Subjective assessment based on ventricular enlargement and sulcal depth

B

General impression consistent with the clinical picture

C

Objective scoring systems (e.g., Medial Temporal Lobe Atrophy, Global Cortical Atrophy, Koedam Score)

D

Quantitative measurements (using volumetric analysis software)

E

Other

How often do you use a scoring system or quantitative measurement?

*

(For those who answered in the previous question that they use an objective scoring system or quantitative measurement)

A

I use it regularly

B

I use it for some patients

C

I don't use it; I assess based on my clinical experience

D

I know the scales but rarely use them in practice

Which scales do you use?

*

(You can write more than one with "Other" option)

A

MTA (Medial Temporal Atrophy)

B

GCA (Global Cortical Atrophy)

C

Koedam Score

D

Fazekas Scale

E

Volumetric software (e.g., NeuroQuant, volBrain, etc.)

F

Other

If you have a disagreement with your colleagues regarding the severity of brain atrophy, how do you usually solve it?

*

A

We conduct a joint re-evaluation

B

I refer to the radiology report

C

I seek a second opinion from another specialist

D

Clinical decision-making takes priority; I focus more on the patient than the imaging

E

The disagreement is not very significant; it doesn’t change my treatment approach

F

Other

How often do you take into account the Radiology Department's opinion on brain atrophy?

*

(Radiologists can skip this question)

A

Always

B

In unclear or critical cases

C

Rarely

D

Never

E

Other

If an objective, practical brain atrophy score were developed, would you consider using it in your clinical practice?

*

A

Definitely yes

B

Yes, if it is practical

C

I'm uncertain; it depends on ease of use

D

Probably not

E

No, I find clinical assessment sufficient

F

Other

During the evaluation of brain atrophy, do you consult with other specialties (e.g., neurology, psychiatry, radiology, etc.)?

*

A

Yes, I frequently consult

B

I consult in special cases where I deem it necessary

C

Rarely

D

No, I make decisions based on my own evaluation

E

Other

If you consult, which specialties do you consult with?

*

A

Neurology

B

Neurosurgery

C

Radiology

D

A

Grade 0 (Normal: No atrophy, plump hippocampus)

B

Grade 1 (Mild: Widening of choroid fissure only)

C

Grade 2 (Moderate: Mild widening of temporal horn)

D

Grade 3 (Severe: Moderate loss of hippocampal volume, marked widening of temporal horn)

E

Grade 4 (Very severe / End-stage atrophy)
