Qvarlander S, Ambarki K, Wahlin A, Jacobsson J, Birgander R, Malm J, et al.
Acta Neurol Scand
. 2016 Jul;
135(5):576-584.
PMID: 27388230
Objectives: Increased aqueduct cerebrospinal fluid (CSF) flow pulsatility and, recently, a reversed CSF flow in the aqueduct have been suggested as hallmarks of idiopathic normal pressure hydrocephalus (INPH). However, these...

Graefes Arch Clin Exp Ophthalmol
. 2015 Aug;
253(11):1979-83.
PMID: 26267751
Purpose: To investigate the effect of aging on ocular parameters, including intraocular pressure (IOP), measured with different tonometry methods in healthy young (HY) and healthy elderly (HE) subjects and to...

Ambarki K, Wahlin A, Zarrinkoob L, Wirestam R, Petr J, Malm J, et al.
AJNR Am J Neuroradiol
. 2015 Aug;
36(10):1816-21.
PMID: 26251434
Background And Purpose: The arterial spin-labeling method for CBF assessment is widely available, but its accuracy is not fully established. We investigated the accuracy of a whole-brain arterial spin-labeling technique...

Wahlin A, Ambarki K, Birgander R, Wieben O, Johnson K, Malm J, et al.
AJNR Am J Neuroradiol
. 2013 Mar;
34(9):1740-5.
PMID: 23493888
Background And Purpose: 4D PCMRI can be used to quantify pulsatile hemodynamics in multiple cerebral arteries. The aim of this study was to compare 4D PCMRI and 2D PCMRI for...

Vagberg M, Lindqvist T, Ambarki K, Warntjes J, Sundstrom P, Birgander R, et al.
AJNR Am J Neuroradiol
. 2012 Sep;
34(3):498-504.
PMID: 22976234
Background And Purpose: Brain atrophy is a manifestation of tissue damage in MS. Reduction in brain parenchymal fraction is an accepted marker of brain atrophy. In this study, the approach...

Ambarki K, Lindqvist T, Wahlin A, Petterson E, Warntjes M, Birgander R, et al.
AJNR Am J Neuroradiol
. 2012 May;
33(10):1951-6.
PMID: 22555574
Background And Purpose: Brain size is commonly described in relation to ICV, whereby accurate assessment of this quantity is fundamental. Recently, an optimized MR sequence (QRAPMASTER) was developed for simultaneous...

Israelsson H, Birgander R, Ambarki K, Eklund A, Malm J
Acta Neurol Scand
. 2011 May;
125(3):163-70.
PMID: 21554255
Objectives: Dilated ventricles and gait disturbances are common in the elderly, and these are also features of the treatable syndrome idiopathic normal pressure hydrocephalus (INPH). Many studies report an association...

Ambarki K, Wahlin A, Birgander R, Eklund A, Malm J
AJNR Am J Neuroradiol
. 2010 Nov;
32(2):408-12.
PMID: 21051511
Background And Purpose: Automatic assessment of brain volumes is needed in research and clinical practice. Manual tracing is still the criterion standard but is time-consuming. It is important to validate...

Wahlin A, Ambarki K, Birgander R, Alperin N, Malm J, Eklund A
AJNR Am J Neuroradiol
. 2010 Jul;
31(9):1645-50.
PMID: 20595369
Background And Purpose: The PVI(CC) of the craniospinal compartment defines the shape of the pressure-volume curve and determines the damping of cyclic arterial pulsations. Despite no reports of direct measurements...

Bouzerar R, Ambarki K, Baledent O, Kongolo G, Picot J, Meyer M
Phys Rev E Stat Nonlin Soft Matter Phys
. 2005 Dec;
72(5 Pt 1):051912.
PMID: 16383650
We address the question of the ventricles' dilation as a possible instability of the intracranial dynamics. The ventricular system is shown to be governed by a dynamical equation derived from...
